PhD candidate Sneha Sanjeevini Awarded 2020 Zonta International Amelia Earhart Fellowship

Congratulations to U-M Aerospace PhD candidate, Sneha Sanjeevini, for being awarded a 2020 Zonta International Amelia Earhart Fellowship for her research on sensor failure detection and diagnosis.| Short Read

Under the mentorship of Professor Dennis Bernstein, Ms. Sanjeevini is developing new techniques for detecting and diagnosing faulty sensors. Sensors are critical components of all technological systems, and sensor failure in aircraft can result in catastrophic events. Ms. Sanjeevini focuses her work on a specific topic in systems and control theory, namely input estimation, which uses output measurements to estimate the unknown system input.

“In order to detect and diagnose sensor failures, I will use input estimation to estimate the measurements that are expected from a sensor and then compare them with the actual sensor measurements,” Sanjeevini explained. “I am currently working on the theory of input estimation and developing new input-estimation algorithms. I will then apply these algorithms to sensor fault detection and diagnosis. The ultimate goal of my research is to prevent car and aircraft accidents by enhancing sensor reliability.”

Sneha Sanjeevini received her undergraduate degree in Electronics and Instrumentation from the College of Engineering Trivandrum, India. She completed her master’s degree in control and instrumentation from the Indian Institute of Technology Madras, India. She is currently in her fifth year in the U-M Aerospace Engineering PhD program. She has given talks at major conferences in Milwaukee and Philadelphia.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
