Tunmise Raji came to RIT with a vision to harness technology for global good. He’s leaving prepared to advance energy solutions for underserved communities. Raji, a Ph.D. candidate at Golisano Institute for Sustainability (GIS), is one of 56 people who will be honored at Commencement on May 9 in the doctoral hooding ceremony. A native of Nigeria, Raji grew up in a nation known for power insecurity. In some areas, frequent power outages due to aging and overstressed infrastructure and a shortage in supply result in residents going weeks without having access to electricity, a common challenge in many countries in Sub-Saharan Africa. After studying electrical engineering abroad, Raji completed his master’s degree at Carnegie Mellon in 2019, where he studied under Professor Nathan Williams. After earning his master’s degree, Raji worked in Uganda for two years, developing renewable energy projects aimed at electrifying small villages across East Africa. He was eventually invited to apply for a new Ph.D. opportunity in GIS by Williams, who joined RIT in 2020. “From taking his class, I knew we had a shared interest in Sub-Saharan Africa and data-driven research, so it felt like the perfect opportunity,” Raji said. Raji’s research focuses on using sustainable infrastructure development to drive progress in the Global South. In one recent study with Williams and fellow Ph.D. student Courage Ekoh, he examined the Nigerian energy landscape, advocating for a hybrid approach that blends centralized grid and off-grid sustainable solutions to create a more resilient, inclusive power system. Raji credits much of his growth to the mentorship and diverse learning environment within GIS. Along with the direct impact that Williams made on him, he also highlighted the impact of Professor Callie Babbitt’s classes, which emphasized the three interconnected legs of sustainability—environmental, economic, and social. “Being in GIS, you’re able to interact with people from all walks of life,” Raji said. “It really helps you to put your research in the right perspective. It’s not siloed in one particular field, but actually more applicable to the rest of the world.” Outside of the classroom, Raji has attended and presented at conferences in Morocco and China, organized a two-week training on remote sensing for the National Institute of Statistics in Rwanda, and landed a pair of fellowships through the Environmental Defense Fund. In those fellowships, he helped develop a transportation electrification plan in Durham, N.C., and examined strategies with Element Fleet Management to shift the company’s fleet from internal combustion engines to electric fleets. He plans to continue that momentum beyond graduation. “Tunmise has been such a pleasure to work with,” Williams said. “He is full of ideas and so driven by curiosity. He really made my job as an adviser easy. It is fantastic to see our students not just pushing scientific boundaries but also using their skills to benefit the global community more directly.”  

Billions of Apple devices are used in the world daily, and it’s important for their quality to be consistent. Graduating color science master’s student Andrea Avendano Martinez will be helping do just that as a camera color science engineer for Apple in Cupertino, Calif., starting this June. “Essentially, I will be making sure that for all the camera modules that they manufacture, the color quality and the color capacity are the same,” explained Avendano Martinez. Avendano Martinez feels well prepared to enter the workforce thanks to the connections she’s made with many RIT alumni who are working in the same industry. The Munsell Color Science Laboratory is one of the oldest research centers on campus and hosts the only color science Ph.D. program in the United States. “RIT’s color science is unique in the world in its focus on human color perception and application to modern technologies,” said Michael Murdoch, head of the Integrated Sciences Academy. “The Munsell Color Science Laboratory has a long history of research and application to display systems, including modern high dynamic range televisions and augmented reality systems. Contributions over the years include calibration methods, tone-mapping operators, perceptual image quality scales, and models of spatial color differences, transparency, and brightness.” Avendano Martinez credits the reputation of the program in helping her land a job with Apple. “These companies are looking specifically at the Munsell Color Lab and getting students from these labs because the quality of the education is so high. They already know they are getting good color scientists,” said Avendano Martinez. “They prepared me super well. Getting recognized by these companies is amazing and great to be a part of.” Avendano Martinez came to RIT from Gurnee, Ill., as an undergraduate student to study motion picture science, which was a perfect blend of her interests in creative filmmaking and STEM skills. After graduating in 2022, she did two internships at Dolby. She learned about opportunities with that company after hearing an alumnus speak to a student organization. In her first internship she worked with Dolby Vision for content creation where she helped showcase new technologies. Her second was more focused on color science. “I was a color and vision science engineer and I made my own research project,” said Avendano Martinez. “It was like a mini thesis, and I was able to present my project at a conference. That experience led me to get a master’s degree. Now that I’m ending my time here at RIT, I’m excited for this new chapter and what other opportunities it may bring!”
