Northrop Grumman Systems Corporation (NGSC Sector: Mission Systems) Linthicum Heights, MD Senior Principal Systems Engineer, Future Technical Leaders Program, Supervisor: Alla Aksel, Ph.D., 2020-present

• Currently maintaining Active Security Clearances (Top Secret and Special Access Program).

• Recognized as “Top Performer” in FY2021 (awarded to <10% of total employees across multiple sectors) and

“Excellent Performer” in FY2022 (awarded to <35% of total employees across multiple sectors).

• Program Manager (PM)/Principal Investigator (PI) of several internal (IRAD) and external (CRAD) RF & EOIR R&D seedlings and programs, which have fostered new business development efforts across NGMS Advanced Technology Operating Unit (Total Awarded IRAD/CRAD efforts as PI/PM: ~$1.5M USD).

• Served as PI for 9-month, $500,000 DARPA MTO Seedling Program effort (Project Title: High Performance Electron-Based Abrupt-Junction Diamond Devices; DARPA MTO Program Manager: Thomas Kazior, Ph.D.), which includes leading proposal effort, leading monthly reports/final report/final presentation/other miscellaneous deliverables to customer, interfacing with customer on frequent basis, serving as primary technical point of contact for seedling program, and leading overall technical execution of seedling program.

• Led or co-wrote a variety of CRAD abstract and proposal efforts, such as NSTXL Microelectronics Commons (in preparation), NextFlex Advanced Manufacturing (awarded), DARPA UWBG-S (under review), DARPA ELGAR, DARPA H2, DARPA NGMM (awarded), DARPA THREADS (awarded), and DARPA HOTS.

• Led 5 university research collaboration partnerships, which span a variety of emerging research efforts, such as developing high-performance N+ diamond electronics, developing diamond/c-BN heterostructures, developing homoepitaxial growth of c-BN epitaxial films on c-BN seeds, developing high-power linear Geiger-mode GeSn single-photon avalanche detectors (SPAD), and developing graphene-based multi-spectral LWIR imagers.

• Led the design, modeling/simulation (i.e., atomic-scale and device), fabrication, and characterization of a unique range of BiCMOS production (i.e., bulk silicon & SOI) and emerging technology program efforts (i.e., 2D Materials, CNTs, Flexible Electronics, EO/IR, and UWBG materials) for applications in radar, communications, electronic warfare, radiation-hardened electronics for space systems, and other RF electronics & EO/IR systems.

• Lead/co-author a total of ten invention disclosures/trade secrets (1x invention disclosure led to “New Technology Award” and 1x invention disclosure led to “Innovation Award”).

• Leading Model-Based Systems Engineering (MBSE) based modeling (i.e., CAMEO) for restricted radar program. Thorlabs Quantum Electronics, Inc. Jessup, MD

Semiconductor Fabrication Process Engineer, Supervisor: Frederick Gleaton, M.S. 2018-2019

• Developed and manufactured optoelectronic semiconductor components (i.e., GaAs, InP, and LiNbO3), including optical amplifiers, optical waveguides, electro-optic modulators, quantum-cascade lasers (QCL), inter-band cascade lasers (ICL), vertical-cavity surface emitting lasers (VCSEL), and other compound semiconductor subsystems for applications in optical tweezers and optical coherence tomography (OCT) imaging.

• Led scalable foundry efforts to realize device, project, and customer objectives; these efforts led to a total revenue of > 3 million USD and > 90% on-time delivery (OTD) in span of 12 months. Massachusetts Institute of Technology Lincoln Laboratory Lexington, MA Graduate Technical Intern, Supervisor: Gary Smith, Ph.D., Collaborator(s): Richard Molnar, Ph.D. 2017

• Aligned fiber coupling system and performed coupling efficiency measurements for high-powered diode lasers.
