STEMinism: Lassonde 50:50 Gender Initiative recognized in Ontario Professional Magazine

The Lassonde School of Engineering at York University is Canada’s first engineering school to set a goal of 50:50 gender balance

“By twelve years old, most girls can’t do math.”
“If they study science, they will have to give-up arts or
sports.”
“High school physics is too hard for girls anyways.”
It is not uncommon to hear these statements from parents, teachers, friends, relatives, classmates and girls themselves. Possibly without realizing it, an unconscious bias has been established in Canadian society dissuading girls from the fields of math and science. It’s no wonder that so few girls and women become engineers. In 2015, women held only 12 per cent of licenses to work in the engineering profession across Canada. Almost 25 years ago, I was part of a speaker’s panel that discussed how to encourage more women into professions. I spoke about engineering, and recent female graduates of law and medicine spoke about their respective professions. Today, the professions of medicine and law are leaders in inviting and encouraging women into their fields, but engineering has barely made a dent. From 1991 to 2013, the undergraduate enrolment of women in engineering programs across Canada went from 16.1 per cent to 19.0 per cent, an increase of just 2.9 per cent over a 22 year period.

A tremendous amount of outreach and effort by numerous organizations over these years has been focused on drawing girls into engineering with programs like science camps, coding sessions and robotics clubs. As valuable as these activities are, the profession has seen little change in its gender split. Canada needs more women in engineering. Research has shown that if a group includes more women, its collective performance rises. Gender diversity also shows a positive effect on team innovation in ground-breaking research. With Canada ranking just 26’h globally for business innovation, this is clearly an opportunity to drive economic growth with a diverse set of contributions. It is predicted that Canada is facing major impending labour shortages in fields like engineering. By excluding women from the engineering profession, a highly competent and productive segment of the labour market is currently underutilized. Thus, promoting women’s advancement in engineering would diversify this field that is expected to power much of Canada’s economic engine, meet projected labour demands, and boost innovation and productivity.
The Lassonde School of Engineering at York University has taken a leadership role to address this complex problem of women’s underrepresentation in engineering. On March 3, 2015, it made a bold announcement during National Engineering Month and ahead of International Women’s Day. The School launched the Lassonde 50:50 Challenge to become the first engineering school in Canada to reach a 50:50 gender balance. “Achieving a 50:50 gender balance should be a necessity for every engineering school. It is the single most significant change we can make to improve engineering education in Canada,” said Janusz Kozinski, founding Dean of the Lassonde School of Engineering at the time of the launch. The Lassonde 50:50 Challenge is the first of its kind in Canada. I was selected as the School’s first Assistant Dean, Inclusivity and Diversity to lead this project. Alongside me are two honourary co-chairs, Silicon Valley entrepreneur and philanthropist Sandra Bergeron, and Katty Kay, journalist and coauthor of The Confidence Code and Womenomics. It is a real honour to be a part of this team affecting change on an issue so close to my heart. I believe achieving this goal calls for a comprehensive approach including changing cultural biases and beliefs about what men and women do best throughout their education, training and professionalization. At the public and high school level, we will support initiatives that help girls view themselves as competent in math and science, and help girls associate their desire to help people and society with being an engineer. For example, girls are interested in solving climate change, ending poverty and designing tools that help people – all outcomes that an engineer can contribute to. So we will focus on programming that helps girls find a fit between their own values and what they perceive engineers do. The Lassonde School has been created to be the home of Rennaissance Engineering: a place where students are free to explore their passions and gain different perspectives from the world around them. Our Renaissance undergraduate curriculum will give students a truly multi-disciplinary education. With the opportunity to take courses in law, business and international development alongside engineering, students can explore ideas such as social entrepreneurship. We will experiment with the teaching environment to support female students’ full participation. The “flipped classroom” model at Lassonde encourages students to discover answers in small groups working collaboratively with professors and classmates. This marks a shift away from traditional lectures and textbook learning, toward a focus on problem-solving and hands-on learning. In addition, inclusivity training for professors and students will create an “identity safe” climate to allow for the full participation of everyone regardless of their gender identity.

Our co-op and internship programs will provide specialized training to help students prepare, before entering the workplace, how to confront gender bias and encourage gender inclusive policies at the companies where they work. Our goal is to create allies in men and women within the engineering profession to reduce stereotype threats that can discourage women from staying in engineering, as their profession of choice, after their education. Lastly, we will review the pathways for women into post-graduate studies and professorships to increase the role models for female students and the research
outcomes for the School.

The Lassonde School of Engineering is grateful for the leadership of the Association of Ontario Land Surveyors (AOLS) in helping us reach the goal of gender balance. In addition to the eleven financial awards that the AOLS currently provides for Lassonde students, this fall the AOLS introduced two new Women in Geomatics Engineering Entrance awards designed specifically for female high school graduates. The inaugural winners are Amelia Kishlyansky and Krystel Reyes. Now is the time for all of us to embrace this challenge. I look forward to working with the many experts and engineering schools that are also committed to this long overdue social change. Reaching 50:50 is a bold ambition and one that I am confident we will achieve, together.

York U-led laser instrument to help bring home asteroid sample by NASA mission

The OSIRIS REx Laser Altimeter OLA undergoing testing

Michael Daly, a York University researcher, is the lead scientist on a laser altimeter that will map the surface and create a 3D model of the asteroid Bennu during a NASA mission launching in 2016.

The instrument will also help to guide the spacecraft on the OSIRIS-REx Asteroid Sample Return Mission to a safe spot, where it will grab a sample to bring back to Earth.

“From a science perspective, we need to understand the current state and the evolution of the asteroid,” said Daly, a Lassonde School of Engineering professor, noting one of the goals of the mission is to understand the organic material content of asteroids.

“The sample will provide a snapshot of materials available during the formation of the solar system.”

The OSIRIS REx Laser Altimeter (OLA)

By contributing the instrument – the OSIRIS-REx Laser Altimeter (OLA), an advanced LIDAR (Light Detection And Ranging) – to the mission, Canada will get a portion of that sample. The mission is expected to return 60 grams of the asteroid, but more than a kilogram is hoped for. It will provide Canadian scientists the first-ever direct access to a pristine asteroid sample, according to the Canadian Space Agency (CSA), which funded the instrument.

OLA is more accurate and has a higher resolution than previous altimeters that have been aboard any previous planetary missions, which means better mapping of the asteroid’s topography.

“A lot of LIDARs stare straight and depend on the spacecraft to move around and provide mapping, but we actually do a raster scan, like the way an old cathode-ray tube TV works,” said Daly. “It’s more like taking a range picture than getting a single measurement. The fidelity of information will be higher.”

Bennu, which is about 500 metres in diameter, is of particular interest because it is one of the most potentially hazardous asteroids presently identified, with a small chance of hitting Earth in the 22nd century. The mission will allow the team to study and track the asteroid’s orbit, as OLA will provide precise distance measurements from the spacecraft to the rocky surface.

Michael Daly

“That’s important, as an asteroid’s orbit is difficult to predict over the long term; because asteroids are so small, they get pushed around by small forces,” said Daly. “Understanding how this asteroid has been pushed around, along with its surface and shape properties, will help us to track asteroids better in the future. And thereby we can provide improved predictions about probability of collisions with the Earth.”

OLA, about the size of two bread boxes, will also help navigate the spacecraft to the best location for grabbing a sample. But that won’t happen for a while.

“The main part of the mission, the proximity operation, starts seven or eight kilometres from the asteroid,” said Daly. “Then, it’s a long process of getting to know the asteroid well enough and its non-uniform gravity field well enough to be able to get down and touch the surface and grab a sample.”

That phase will start in late 2018.

As the prime contractor for the CSA, MacDonald, Dettwiler & Associates (MDA), together with its industrial partner Optech, designed, built and tested the instrument.

York University’s Daly is the lead instrument scientist for OLA. The team also includes professors Alan Hildebrand, University of Calgary; Ed Cloutis, University of Winnipeg; Rebecca Ghent, University of Toronto; and Catherine Johnson, University of British Columbia.

Recently delivered to Lockheed Martin in Denver, OLA will now be integrated with the NASA spacecraft for launch in September.

Climate change altering Greenland ice sheet and accelerating sea level rise, says York U professor William Colgan

The Greenland ice sheet has traditionally been pictured as a bit of a sponge for glacier meltwater, but new research has found it is rapidly losing the ability to buffer its contribution to rising sea levels, says a York University researcher.

York University Professor William Colgan, a co-author on the study published Jan. 4 in the journal Nature Climate Change, helped analyse data from three expeditions to the Greenland ice sheet in 2012, 2013 and 2015. The research was done in conjunction with lead researcher Horst Machguth of the Geological Survey of Denmark and Greenland, Mike MacFerrin of the University of Colorado at Boulder and Dirk van As of the Geological Survey of Denmark and Greenland Copenhagen, Denmark.

In 2013, Colgan spent five weeks with the team drilling firn cores in the interior of the Greenland ice sheet. Firn is multi-year compacted snow that is not as dense as glacier ice. Instead, it forms a porous near-surface layer over the ice sheet. Dropped off by a ski-equipped US Air National Guard C-130 Hercules in minus 40 degrees Celsius weather, with 6,000 kilos of supplies and equipment, the team set up several camps and drilled a series of shallow firn cores about 20 metres deep during their time on the ice sheet.

“We were interested in the thin porous near-surface firn layer, and how its physical structure is changing rapidly with climate change,” said Colgan, a professor in the Lassonde School of Engineering at York University. “The study looked at very recent climate change on the ice sheet, how the last couple of years of melt have really altered the structure of the ice sheet firn and made it behave differently to future melt.”

Ice sheet

The researchers also towed a radar unit behind their skidoos to gather profiles between core sites along a 100-kilometre path from the low elevation ice sheet margin into the high elevation ice sheet interior. They analysed the firn cores on the spot by cutting them into small sections to quantify their properties, such as their density, so they could compare them with samples collected the following year. “The year-on-year firn changes were quite dramatic,” said Colgan.

The team was surprised by what they found. An extreme melt that occurred in 2012 caused a layer of solid ice, several metres thick, to form on top of the porous firn in the low elevation areas of the ice sheet. “In subsequent years, meltwater couldn’t penetrate vertically through the solid ice layer, and instead drained along the ice sheet surface toward the ocean,” said Colgan. “It overturned the idea that firn can behave as a nearly bottomless sponge to absorb meltwater. Instead, we found that the meltwater storage capacity of the firn could be capped off relatively quickly.”

As Machguth said, “Basically our research shows that the firn reacts fast to a changing climate. Its ability to limit mass loss of the ice sheet by retaining meltwater could be smaller than previously assumed.”

Because the models scientists use to project Greenland’s sea level rise contribution do not presently take firn cap-off into consideration, it means that Greenland’s projected sea level rise due to meltwater runoff is likely higher than previously predicted. Getting this newly observed physical process into these models is an important next step for the team.

Using unmanned aerial vehicles, Colgan also plans to begin surveying the changes in ice sheet surface reflectance caused by the development of massive ice layers associated with firn cap-off. There are preliminary indications that firn cap-off is also occurring in the ice caps of the Canadian High Arctic.

Casey Moore and Jacob Kloos, two graduate students in the Lassonde School of
Engineering’s Earth and Space Science (ESS) Program have been awarded the NASA
Group Achievement Award for their contributions to the Curiosity Rover mission.
Moore and Kloos are members of the Curiosity’s Science and Operations teams and
are part of the team that decides and plans what the rover will do on the Martian
surface each day.

“This is a significant honour in space exploration where contributing as a team is the
key to success” said Moore and Kloos’ advisor, Prof. John E. Moores. “It is fantastic
that our students have the opportunity to become directly involved in running a
space mission by operating a robot on another world.”

For MSc student Kloos, working on a space mission is an opportunity “to see how
things really work in the background. You always hear about results from Mars, but
it is cool to understand the complex mechanics of doing science on another planet
and to be a part of that.” PhD student Moore has been a part of the mission for
nearly two years and notes that “not many people can say they go to work on Mars.
It’s exciting working on such a large project with top researchers from all around
the world. I don’t think many people have an appreciation for just how much work is
put in my hundreds of dedicated people on a daily basis to keep the rover healthy
and productive.”

In specific, the award cites the student’s contributions to “exceptional innovations in
rover surface operations leading to significantly improved Mars Science Laboratory
prime mission performance and science return.” It is the 11th NASA Award for
members of Prof. Moores’ Planetary Volatiles Laboratory in the last six years.
