The best way to contact me is via email to I typically check my email multiple times during the day as part of other activities. I currently live in Annapolis, MD.


I began my career as an engineer. In 1995, I graduated from the University of Pennsylvania with a PhD in Electrical Engineering. My thesis involved the design of an analog neural network using full-custom VLSI. I used the neural network to model aspects of the auditory cortex for speech recognition.

After Penn, I spent the next 12 years working for graphics companies in Silicon Valley. Along the way, I built midrange graphics cards for SGI, worked at an amazing startup company called Gigapixel, and spent 5 years designing products for nVidia. Some of the patents I've been a part of include: 6,646,648, 6,980,209, 7,245,302, 7,355,603, 7,417,637, 7,565,490, 7,589,741, 7,697,009, 7,692,654, 7,705,846, 7,808,512, 7,876,332, 7,911,470, 7,996,622, 8,004,522, 8,040,357, 8,098,257, 8,325,203, 8,547,395, and 8,860,722.

In 2007, I left nVidia to pursue a career in teaching. My teaching credential work was done at San Francisco State University, with my student teaching taking place at Lowell High School. In the Spring of 2009, I received my teaching certification in Advanced Mathematics. After teaching in high school for several years, I moved on to community college where I teach or have taught geometry, statistics, calculus, college algebra, and trigonometry.

When I quit engineering, I also decided to pursue a lingering passion: art. I took classes at the Academy of Art in San Francisco where I got the chance to study with Henry Yan. I later moved to Baltimore where I've been studying various forms of drawing and painting including landscapes, figures, and still life with both charcoal and oils.
