Research Information

I have research in the areas of test of analog and mixed signal circuits, design of  on-chip wireless systems, and  IC interconnect and package characterization My recent work  combines electronic design, packaging, and embedded software design for wireless sensor systems in collaboration with leading researchers in entomology (mosquitos, flies, etc.), power systems, and biomedicine.  Current designs and prototypes include microclimate weather stations and wireless temperature sensors for blood monitoring. I am also developing workshops for training industry engineers IC test of analog devices.
