RELEVANT PROFESSIONAL TRAINING
∙ Engineering Leadership
I lead a small team of engineers to deliver results on a high visibility project with nation-wide collaborators, which featured as the cover article of an IEEE magazine.
∙ Technical communication skills
I have excellent technical writing skills, and have written a number of conference papers. I also have a Journal article in review. Having presented my research at numerous international conferences, I have polished skills to communicate with large technical audiences.
∙ System level experience on multiple radar projects, from Concept to Field deployment
I have significant experience in radar system design and integration. I also have experience with radar signal processing and handling large data volumes.
∙ Specialized skills for sub-system development
Hands-on experience with Ansoft HFSS, Cadence Allegro, Quartus II, VHDL, C and IDL (a Fortan- based programming language that has some similarities to MATLAB). I bring antenna and microwave engineering, PCB design and digital hardware experience to the table. Very familiar with use of lab equipment like spectrum/network analyzers, peak power meters and antenna pattern measurement facilities.

· Integration of phased-array radar sub-systems (Nov. ‘11 - present)
I currently work with a team of Engineers who have been responsible for development of various sub-systems on a phased-array radar project. I am responsible for integration of the data-acquisition code with an FPGA-based control subsystem. Using an in-house near-field scanning facility as a diagnostic, I am assembling the passive antenna array with a radome and transmit/receive modules.
· Simulation of a phased-array spaced-antenna radar (July ‘10 - present)
I developed a monte-carlo based phased-array radar simulator using IDL – a Fortran-based programming language similar to MATLAB. I used this simulator to investigate spaced-antenna wind estimation algorithms to retrieve 2-D wind fields using an X-band phased-array radar.
· Lead Engineer for an X-band radar during VORTEX2 (May. ‘09 – July ‘10)
I lead a small team of Engineers for operation and maintenance of an X-band radar in $10M dollar field experiment. The field experiment spanned about 2 months a year, where we would nomadically roam the great plains of central western USA on a pickup truck with our radar mounted on. I was also responsible for quality controlling the collected data and sharing them with collaborators.
· Design and development of a solid-state pulse compressed radar (Aug. ‘08- Apr. ‘09)
I lead a small team of Engineers to develop and integrate various sub-systems on a low peak power solid-state radar. The sub-systems developed were real-time data acquisition software that implemented pulse-compression, FPGA-based control system and the RF sub-system. This system is now being integrated with the phased-array antenna system.
· Upgrades on a Magnetron based dual-polarized radar (Jun. ‘07 – Jul. ‘08 )
I developed a voltage-translator PCB using Cadence Allegro to replace an already existing but problematic component on the radar. I also upgraded the FPGA sub-system to a state machine based controller. I was also responsible for field experiments that with this radar, and subsequent data processing and quality control.
University of Colorado at Boulder, 2004-2007
· Temperature retrieval from meteor echo decorrelation times (Jun. ‘06 – May ‘07)
Investigated algorithms to extract upper atmospheric temperature from radar echo decorrelation times. This involved programming using IDL and presenting results at a conference.
· Design and testing of receiver sub-system for a VHF radar (Feb. ‘05 – May. ‘06)
I was responsible for the design and layout of a VHF receiver sub-system on a PCB using Cadence Allegro. I also assembled and tested the PCB and packaged it using machining tools available in house.
