Dr. Lele is an electronics engineer with an expertise in industrial circuit designs and development of integrated microsystems. Her research interests include analog/digital circuit design and analysis, signal processing and mixed-signal integrated circuits.
On account of her work experience, she specializes in display port interfaces, use of electrical laboratory equipment and simulation tools for PCB/IC design, and numerical modelling. She has also worked with optical networking equipment, EDFAs, and been involved in functional and component level test development for optical amplifiers.
Prior to joining Exponent, she was involved in design, development and deployment of end to end manufacturing test solutions for optical networking equipment at ADVA Optical Networking. Specifically, Dr. Lele was involved in board level and component level functional testing of WDM telecom devices (Erbium Doped Fiber Amplifiers) using NI TestStand and LabVIEW.
Dr. Lele has been part of the team involved in design of the DisplayPort AUX/I2C interface at AMD, Inc. (Advanced Micro Devices, Canada) with GF’s 20nm and 14nm technology. At AMD, she performed simulation, characterization, timing and power analysis of analog circuits for IO interface and custom macros using Cadence, Synopsys, Apache tools.
As part of her PhD dissertation, Dr. Lele has worked on integration of control circuits for power relays with GE Multilin. The project involved developing a microsystem methodology for detecting voltage and current disturbances in high-voltage power distribution lines. The prototype system employed piezoelectric transformer in combination with Hall-effect sensor with an integrated signal processing unit.
Prior to graduate studies, at Siemens (India), Dr. Lele’s work included design improvisation of ‘25kVA underslung type coach converter' typically used in air conditioning systems in Indian Railway coaches. She was also part of the team developing the 500kVA converter for power car of super-fast trains of Indian Railways, and its corresponding control panel, for the air conditioning and lighting loads in each coach.
