Miloš Janković was born in Serbia. He completed his B.S. degree in Electrical Engineering in 2003 at the University of Arkansas at Fayetteville and received his M.S.E.E. in 2005 from the University of Colorado at Boulder. He is pursuing a Ph.D. in electromagnetics with an emphasis in low noise microwave circuits and broadband power amplifiers. He enjoys skiing, biking and playing basketball.

Negar Ehsan was born in Tehran, Iran, in January 1982. She received the B.S. and M.S. degrees in Electrical and Computer Engineering and a minor in Applied Mathematics from the University of Colorado at Boulder in 2006. She was the recipient of the 2006 distinguished senior award from the Department of Electrical Engineering. Currently, she is working toward the Ph.D. degree in Electrical Engineering. Her current research interest is designing wide-band passive circuits utilizing rectangular coaxial lines around a wide-band high power amplifier which is a “MMIC-less” architecture and a replacement for solid state traveling wave tubes. She is also interested in thick frequency-selective surfaces, and impedance tuning networks.

Luke Sankey was born and raised in Washington State, and received his B.S.E.E. from Seattle Pacific University in 2001. He worked for Honeywell Aerospace in Redmond, WA, for 5 years writing software for their commercial weather radar products, and then came to Colorado in 2005 and received his M.S.E.E. from CU Boulder in 2007. If not otherwise occupied, you can find him outdoors riding motorcycles, skiing, bicycling or playing Frisbee. Luke is currently working towards his Ph.D. in electromagnetics on a research project involving a feedback-controlled impedance tuner, and is survived by his wife and cats, who live in Longmont.

Mike Elsbury graduated with a B.S.E.E. from University of Idaho in 2003 where he concentrated on analog IC design and microwave circuits. Mike then worked for the Boeing company for 2 years as an RF test engineer before returning to school at CU to pursue his Ph.D. His current research, in collaboration with NIST, regards broadband superconducting K-band integrated circuits to optimize the microwave performance of Josephson junction voltage references and quantized arbitrary signal generators. In his copious free time Mike enjoys ultimate frisbee, rock climbing, skiing, mountaineering, mountain biking, kayaking, and backpacking in the Rocky mountains of Colorado.

Nicola Kinzie grew up in a small town in central Kansas. She received her B.S. in Electrical Engineering from Kansas State University in 2006. She then joined Zoya's research group and is currently pursuing a Ph.D. Her research, which is supported by Sandia National Laboratories, centers on the design of an ultra-wideband radar for the detection of nearby, high velocity targets. In her free time, she enjoys cooking, baking, and designing home accents. She's also an avid gamer and loves to curl up with a good book.

Evan Cullens got off the tractor in Kansas one day to join the Navy as an electronics technician specializing in control of nuclear reactors. He then attended Kansas State University, supervising their nuclear reactor and graduating with honors in 2006 with a B.S.E.E, specializing in IC design and microwave circuits. After bidding farewell to his honors project (a transceiver for NASA's future Mars missions), he came to CU where he now works on a cost-effective, solid-state solution to traveling wave tube amplifiers, for EW, radar, IW, and communication systems. In his exiguous spare time, Evan enjoys spending time with his extended family, riding his motorcycle, playing guitar, traveling to foreign countries, and the great outdoors.

Jonathan Chisum is from Seattle, WA, where he recieved a B.S. in Electrical Engineering from Seattle Pacific University in 2003. After working in industry for three years he returned, in 2006, to get his Ph.D. in electromagnetics. He is currently a research assistant in the Terahertz Technology laboratory at the National Institute of Standards and Technology. His research includes the development of a readout and control system for a terahertz multi-pixel, room temperature imaging system. Outside of academics, he enjoys all that the Rocky Mountains have to offer; biking, hiking, climbing, skiing, and camping.

Erez Avigdor Falkenstein was born in Haifa, Israel in 1979. He earned a “Handesaie” degree from Amal Handesaim School Hadera, Israel in 1999 equivalent to a technical associate degree in the United States. From 1999 to 2003 he served in the Israel Defense Force as part of a intelligence technological unit. He is an Electrical Engineering student at the University of Colorado at Boulder since 2004 and is currently working toward a concurrent M.S./B.S. degree. He spends his time in Boulder as an avid amateur cyclist.

Michael Roberg received a BSEE from Bucknell University in 2003 and a MSEE from the University of Pennsylvania in 2006. From 2003 to 2009, Michael worked as a radar system design engineer at Lockheed Martin in Moorestown, NJ. He is pursuing a Ph.D., with his current research focusing on high power microwave amplifier design. In his copious amounts of spare time, Michael enjoys watching college football, sampling fine beers, and enjoying all the outdoor activities Colorado has to offer.
