Notre Dame junior wins big science award for second consecutive year


Notre Dame junior wins Grand Award at metro Detroit science fair; looks forward to getting Ph.D in college.

Malini Mukherji, a junior in Notre Dame’s upper division, earned a Grand Award from the 60th Science & Engineering Fair of Metropolitan Detroit (SEFMD), which was held at Cobo Center on March 15. The title of Mukherji’s project was “A Smart Light-Tracker Using Machine Learning and Dye-Sensitized Solar Cells.” It’s the second year in a row that she earned the Grand Award at SEFMD.

Mukherji’s Grand Award was one of only seven given out in the senior division of the annual science fair, which hosted more than 2,000 competitors from 142 Michigan schools in Wayne, Oakland, Macomb, Washtenaw, Lenawee, Livingston and Monroe counties. As a result of winning the award, she will be attending the Intel International Science and Engineering Fair in Los Angeles in May.

More reliable renewables 
Mukherji said her project this year was inspired by current world trends that show the reduced utilization of fossil fuels and the renewed focus on renewable sources of energy, such as solar energy. Her project specifically investigated ways to more efficiently collect solar energy by tracking the movement of the sun.

“As fossil fuels and other sources of energy are depleting, the world is turning to green energy,” Mukherji said. “A major type of green energy is solar energy and solar trackers provide an effective way to collect the sun’s energy by tilting and rotating to follow the sun’s position throughout the day. Identifying the position of the sun is important for solar trackers. These trackers often use chronological or passive systems to determine the position of a light source.”

Using machine learning, a method for computers to learn without being directly programmed, and dye-sensitized solar cells, Mukherji created an alternative method for solar trackers and other light tracking machines to identify the direction of a light source. 

“This ‘smart’ light tracker can be implemented with current solar trackers and my machine learning program will allow the trackers to always know the position of the sun in real-time and in turn face the sun at the optimum angle,” she explained. “This technology can also be used in any machine that needs to identify the direction of a light source — even robots or autonomous cars.”

In addition to her science fair accolades, Mukherji also recently learned that she was named one of the top 100 students in the latest edition of the Michigan Mathematics Prize Competition (MMPC), which is sponsored by the Michigan Section of the Mathematical Association of America (MAA).

Future college and career plans
Like most high school juniors, Mukherji is looking toward the next level of education with increasing interest.

“In college, I’d like to study materials science and engineering,” she said. “I believe future technological changes will be based on the discovery of new and improved materials. My science fair experiences of the past few years have stimulated my interest in this field. I hope to eventually get a Ph.D in it as well.” 

Mukherji also has some specific career goals in mind as she hopes to someday be a materials science engineer.

“I want to be able to focus on advancing technology that will have a positive impact on global issues like sustainable energy,” she said. “In addition, materials science is a highly inter-disciplinary field. Material scientists solve technological problems that impact all aspects of our lives, from medicine to space exploration. Technological advances of the future will be based on the discovery of new and improved materials. It will be very exciting for me to be a part of this discovery process.”

Mukherji noted that without Notre Dame and its teachers, she probably would not have been as successful as she has over the last several years in her many competitions and events. 

“One of the big motivations for me to continue my science fair projects in high school was to fulfill requirements of Notre Dame’s International Baccalaureate personal project, internal assessments in science classes, and the extended essay for the IB program,” she said. “Since the types of projects I have been doing use knowledge from many disciplines, the contributions of all of my science and math teachers have been equally important. All of those teachers continue to make learning their respective subjects fun, interesting and exciting every single day. Ms. [Jocelynn] Yaroch, for example, is one of those teachers who can really teach us in a unique style that keeps us wanting to learn more. I really appreciate that.”
