Ph.D. in imaging science—Siddharth Khullar

Siddharth Khullar ’09, ’13 (electrical engineering, imaging science) sees a healthy future in wearable devices that help consumers monitor their activity and wellness.

Khullar, now a senior researcher and product innovator at Apple Inc., integrates algorithms and sensing devices in products that advance human-machine interaction and wellness computing.

Drawn to the medical field—but not to medical school—Khullar learned the “engineering-side of medicine” at RIT. He developed a hybrid skill set from his MS in electrical engineering and then his Ph.D. from the Chester F. Carlson Center for Imaging Science. His research included graduate work at the Mind Research Network for Neurodiagnostic Discovery in Albuquerque, N.M., and resulted in image-processing techniques for assessing people with schizophrenia, autism spectrum disorder and bipolar disorder.

A sabbatical during his Ph.D. gave Khullar hands-on experience at the Massachusetts Institute of Technology’s Media Lab. He joined the Camera Culture Group and developed low-cost solutions to mobile health care in developing nations. Khullar repurposed mobile phones as medical screening devices for eye diseases and led the team that built an award-winning retinal imaging system for the early detection of diabetic retinopathy and hypertension. A connection at the Media Lab helped Khullar segue his sabbatical into an internship at Microsoft Research in Redmond, Wash.

Taking a break during his Ph.D. was a bold move his advisers supported—literally. The generosity of his mentor, Stefi Baum, former director of the Center for Imaging Science, funded Khullar’s time in Boston.

That was the tipping point for him.

“My degree helped me not to be afraid of thinking and executing on something that’s different,” he said. “Another thing I learned from my degree—leadership. It’s not just about leading other people. It’s also about leading your own self.”

RIT prepared Khullar to be part of the new paradigm in human-machine interaction. The relationship to technology has “empowered people to have more accessible means to understand their health,” he said. The paradigm continues to evolve.

“Before, it was ‘How do people interact with machines?’” he said. “Now, it’s ‘How do you make machines interact with people?’ There’s a little bit of a difference, a thin line. If you start digging in, that line becomes thicker. The paradigm shift has already happened.”

Khullar knows this first hand. After graduation, he returned to Microsoft as a post-doctoral researcher where he developed new camera-powered health sensing applications and a camera-based heart-rate system using web cameras. His research also contributed to the heart-rate monitor in the Xbox One Kinect camera.

Following Microsoft, Khullar moved to Quanttus Inc., an MIT start-up in Boston, to develop a wearable device for monitoring multiple vital signals. He returned to the West Coast in September 2015 to work on “exciting things” at Apple.

“I was very lucky to be born in the right era,” Khullar said. “This is an incredible age of innovation in health and technology, computer learning and making computers smarter. There are literally no boundaries to how much you can innovate in this space.”
