Sortera Alloys, Inc. is a spin-off from UHV Technologies (aka nanoRANCH) to commercialize a highly innovative patented recycling technology developed with USDOE ARPA-E funding over the last 5 years. Sortera uses its patented artificial intelligence technology for production of low-cost high-quality metal alloys for domestic manufacturing. Sortera's vision is to enable 100% reuse of metals recovered from end-of-life products for manufacturing of similar products.Dr. Kumar's responsibilities include development of a 100 million lbs/yr scrap metal recycling/upcycling facility that can be replicated all around the world to produce highly pure metal streams of feedstock for use in domestic/local industries.

Responsibilities include management and operation of various nanotube/diamond programs, engineering projects, government funded R&D projects, cold cathode research, advanced materials and equipment development, and new product development. Also managed the development of fiber optic and other photonic components under LightMatrix Technologies, Inc. (a spin-off of UHV) and raised $22 M in CY2000 through venture funding. In addition, started International Delta Systems as a subsidiary of UHV, and increased sales from zero to $6 M in CY2001. Obtained orders for large manufacturing equipment from Fortune 100 clients such as Ford, GE, Dupont, Corning, Timex and Nortel.

Responsibilities include management and operation of various field emission projects including high power emitter development for THz devices, magnetrons, medical imaging systems and other applications.

Founded the fiber optics company and managed the development of fiber optic and other photonic components, and raised $22 M in CY2000 through venture funding.

Responsibilities included Electrostatic Deposition of Pharmaceutical drugs for tablet making and inhalers, Plasma Displays, Field Emission Display and other programs, and new project development.

Responsibilities include technical direction of SIDT’s Diamond Field Emission Display (FED) and other programs, development of Internal R&D projects, and new product development.Initiated and led the diamond field emission display (DFED) research and development effort. Leading a team of more than 50 scientists and engineers as the principal investigator of a $7.3 million project to develop a portable laptop computer display screen. Also, responsible for forecasting, planning and overseeing the technology and product development through out the company and its subsidiaries. In addition, helped the management team take SIDT public (current symbol:nnpp) and raise $40 million for DFED technology development.

Responsible for thin film R&D in advanced electronic packaging and flat panel displays. Major accomplishments included invention, development and licensing (to SI Diamond Technology, Inc.) of the DFED technology, development of direct write liquid metal ion source technology for repair of high density interconnect substrates and development of alternate methods for MCM substrate fabrication.Project leader for the Enabling Technologies Project, a $2.75M per year internal R&D effort at MCC. Supervised the development of advanced polymers, various direct metal write technologies, and large area die attach materials. Initiated the effort on diamond thin films for both electronic packaging and flat panel display applications which led to the invention of low work function Amorphic Diamond* technology. Responsible for the thin film development required by various projects in the MCC superconductivity program. Major accomplishments during this thin film research included invention of a new superconducting wire fabrication process, in-situ deposition of high transition temperature superconductor thin films by evaporation and sputtering, thin oxide films for tunnel barriers, deposition of niobium and RF bias sputtered silicon oxide for Nb/SiO2 multi-layer substrates.
