Dr. Sinsky spent the first 13 years of his career at the Johns Hopkins Applied Physics Lab in Maryland.  During that time he was an engineer in the space department where he acquired significant experience designing space-flight microwave hardware including microwave amplifiers and spaceborne phased array antennas.  He held many roles including lead engineer, principal investigator, and project manager for a subsystem on a NOAA satellite. A particularly important theoretical contribution made by Dr. Sinsky was the co-discovery of the microwave stability parameter, µ, which now is implemented in many microwave CAD software packages, and taught in many modern microwave text books.  The discovery of this single stability parameter changed the way engineers analyze microwave circuit stability, by providing a much more insightful approach than provided by Rollet’s pair of stability parameters. Prior to leaving JHU/APL, Dr. Sinsky was promoted to assistant section supervisor in the RF communications Group in the space department. 

At Bell Labs in Holmdel, NJ, Dr. Sinsky worked for several years on fixed wireless access designing agile time division multiple access (TDMA) beamforming software and algorithms.  Then he joined the optical communications and physical enabling technologies organizations respectively, where he used his microwave skills to work on ultra-high speed data and optical communications.  He has given several postdeadline papers at the Optical Fiber Conference (OFC) including work on record sensitivity optical DPSK receivers and the highest reported all ETDM photoreceiver operating at a serial data rate of 107 Gb/s. Additionally, he pioneered the use of electrical duobinary signaling over electrical backplanes (with co-investigator Andrew Adamiecki), making numerous presentations to standards groups, and setting several records for signal transmission over electrical backplane channels and cables.  Currently he is working on ultra-high-speed electrical interconnects striving towards 100 Gb/s serial data rates using advanced signaling techniques, improved channel design, and microwave signal processing.  Additionally, he is working on ultra-high speed and high density electro-optic packaging design methodologies for achieving performance to 100 GHz and beyond for data communications and microwave photonics applications.  He has over 60 refereed technical articles, 7 patents, 2 patents pending, and has given a number of invited talks.
