Undergraduate Research Opportunities
I am always looking for graduate/undergraduate students to work with me. If you are interested in researches on any topic related to power management integrated circuit designs, or, just curious about what power management circuits are, what roles they play in electronics, and how they work, please do not hesitate to contact and visit me! I am more than happy to share my knowledge, from research related to experience in industry or career, with you!
And Yes, undergraduate student can publish good research papers (see the news above :D) I encourage undergrad students work on original research, and will provide as much help as possible.
To join our lab for research, undergrad students will need to have a minimum GPA of 3.5. Students with experiences in circuit designs using Cadence, PCB layout, and FPGA and/or MCU programming are preferred.
Interest Areas
Various types of power management integrated circuits, including but not limited to: wireless power transfer systems, switching power regulators, energy harvesting systems, PA supply modulators, LED drivers, charge pumps and high performance linear regulators.
PI Huang’s Education

PI Huang’s Biography
From 2014 to 2016, I was researching with Prof. Ishikuro-sensei’s group in Keio University, Yokohama, Japan, as a post-doctoral research scientist. During this period, I was focusing on wireless power transfer system designs for biomedical implants, and having a wonderful time traveling to different places in Japan.
From 2016 to 2017, I joined Broadcom Limited in San Jose as a full-time staff scientist, working on power management, analog and mixed-signal integrated circuits, and enjoying the beautiful sunshine in California.
From 2018, I joined as an Assistant Professor in Iowa State University, where I continue my researches on power management circuit designs and enjoy the freedom of research in the academia.
