M. Hassan Kiani, M.S.

Hassan received the A.B. degree in Physics and Engineering from Dartmouth College in 2016 and the M.S. degree in 2018. Hassan developed a fundamental figure of merit and comparison method for hybrid-resonant DC-DC converters.  His work led to some surprising and exciting conclusions that relate to converter optimization given size constraints on active and passive components.  Hassan is currently working at Apple.

Eric Din, M.S.

Eric received his A.B. and M.S. degrees in 2014 and 2016. He built several iterations of a high-density battery management platform that embedded spectroscopic diagnostic tools for Li ion cells configured in large arrays. He designed and synthesized a large digital block that comprised filtering, signal processing and data conditioning for a test chip that also included a quasi-resonant switched capacitor DC-DC converter, which was published at ISSCC 2017. Eric is a co-founder and CEO of Hive Battery, Inc., located in Seattle, WA.

Sarah Pasternak, M.S.

Sarah received her A.B. and M.S. degrees in 2014 and 2016 respectively. She studied tradeoffs among complexity, performance, and power consumption in silicon-integrated digital control systems, and developed a new (fundamental) perspective on quantifying these tradeoffs for digital pulse-width modulation blocks. Her work was verified by an IC controller for an automotive-spec buck converter that was subject to large input voltage transients, strict spectral requirements on the output voltage and current, and conventional regulation requirements. She also developed some fundamental theory (a 2-port charge multiplier treatement) for characterizing and optimizing switched capacitor DC-DC converters.
Sarah is currently an IC designer with Analog Devices in Cambridge, MA.

Christopher Shaef, PhD

Chris received the B.S degree in 2010 and the M.S. degree in 2011 in Industrial Engineering from Helmut-Schmidt University in Hamburg, Germany. He received his Ph.D. degree from Dartmouth College in 2016. At Dartmouth, Chris worked on many aspects of multilevel control for series-stacked photovoltaic cells and vertically-stacked performance digital circuits (microprocessor cores). He also developed new methods of implementing variable regulation and control for high-frequency resonant switched capacitor circuits. He had two papers in the International Solid State Circuits Conference: a DC-DC power delivery prototype that used multiphase interleaving and high switching frequencies to operate with single-digit nH inductance embedded in the PCB; another design targeted battery management: a full 4-quadrant regulated current mode resonant switched capacitor converter with embedded diagnostic capability.
Chris is currently a Power Delivery Researcher in the Circuits Research Laboratory at Intel Corporation.

 Kapil Kesarwani, PhD

Kapil received the B.Tech. and M.Tech. degrees in microelectronics and VLSI from the Indian Institute of Technology (IIT) Madras in Chennai, India, in 2007. He received the PhD from Dartmouth in 2015. Kapil studied the prospects for achieving high power density with resonated switched capacitor circuits. He developed several new architectures, control techniques, and perspectives on multi-mode operation. His 2014 ISSCC paper was one of the first demonstrations of a resonant SC converter implemented in silicon and achieved one of the highest figures of merit for efficiency vs power density in bulk-CMOS at the time.  Kapil is currently an IC design engineer at Allegro Microsystems in Manchester, NH.
