Creating something fundamentally different. An MIT Engine company. https://www.engine.xyz/

As CTO and first employee I created the sub-mm radio location technology, known as MiLo, in my garage. I led a small team to build a total of six commercial pilot systems in a time frame of 100 days wherein we achieved precisions unthinkable in radio location, 500 um 4-sigma. These were piloted to customers and passed FCC pre-screening. Customer feedback drove our next move which was to dramatically miniaturize and cost-reduce the technology by moving up in frequency to D-band 120 GHz millimeter wave and by choosing to implement our tech in a low-cost high-volume silicon process. I led a small team of three to develop a custom chipset and antenna in package (AIP). We successfully piloted the D-band version of technology during a pandemic summer '20 and released the first product in '21. 22 US patents issued from this work.Microlocation demo, you must see it to believe it:https://www.linkedin.com/posts/humatics-corporation_watch-us-demonstrate-a-new-level-of-robotic-activity-6852305494330150912-RsGNExecutive Interview: Greg Charvat, Humatics CTOhttps://www.microwavejournal.com/articles/30883-executive-interview-greg-charvat-humatics-ctoHumatics was the winner of the 2019 NEVY award for 'Rising Star in Tech'https://humatics.com/blog/news_and_events/press-release-humatics-named-rising-star-in-tech-by-the-new-england-venture-capital-association-at-2019-nevy-awards/Humatics Named Cool Vendor in Supply Chain Execution Technologies 2019 by Gartner:https://humatics.com/blog/news_and_events/press-release-humatics-named-cool-vendor-in-supply-chain-execution-technologies-2019-by-gartner/Additional articles on Humatics:http://news.mit.edu/2019/humatics-david-mindell-machine-1002https://www.technologyreview.com/s/608863/a-radar-for-industrial-robots-may-guide-collaboration-with-humans/

As a 4 Catalyzer co-founder and first employee I was responsible for leading the development of the first two proof-of-concept prototypes of the first truly portable MRI. The first one was completed in 123 days, and the second one 6 months later provided significantly higher performance and all subsystems designed in house. The success of these prototypes enabled a large fund raising round. Our entire team won Apple Watches from Jonathan for acquiring our first brain image only 24h after he challenged us to do so. 35 US patents issued from this work.

As a 4 Catalyzer co-founder and second employee I was responsible for leading the initial proof of concept prototypes which were a series of rack-mounted high-channel-count ultrasound systems, built the first lab, hired the initial tech team. We then worked to miniaturize by developing a single-chip ultrasound system (aka ultrasound on a chip); my role in this was to develop the first proof of concept CMUT MEMs transducer elements and once those worked our first CMUT array which the team used to acquire our proof of concept imagery. The success of this first imagery with our own array lead to a $100M fundraising round (see article below). With that completed, I was then asked to 'do the same thing you did at Butterfly' and jumpstart another company under 4Catalyzer, Hyperfine Research Inc. 32 US patents issued from this work. Butterfly is traded publicly on the NYSE as $BFLY.https://www.nytimes.com/2019/04/15/health/medical-scans-butterfly-iq.html?smid=nytcore-ios-sharehttps://www.technologyreview.com/s/532166/with-100-million-entrepreneur-sees-path-to-disrupt-medical-imaging/https://www.technologyreview.com/s/609195/this-doctor-diagnosed-his-own-cancer-with-an-iphone-ultrasound/https://www.prnewswire.com/news-releases/butterfly-network-a-global-leader-in-democratizing-medical-imaging-to-be-listed-on-nyse-through-a-merger-with-longview-acquisition-corp-301177892.htmlhttps://www.butterflynetwork.com/

I developed the MIT Through-Wall Imaging Radar System, this won Best Paper, 2010 Tri Services Radar Symposium and is a MIT Office of the Provost 2011 research highlight. I also Created the project-based radar course at MIT, Build a Small Radar Course (aka the 'coffee can radar'), where everyone builds their own radar out of coffee cans, wood, and other parts. This was the Top-Ranked MIT Professional Education Course in 2011 and has been adopted by numerous universities, institutions, and private organizations.http://news.mit.edu/2011/ll-seeing-through-walls-1018http://ocw.mit.edu/resources/res-ll-003-build-a-small-radar-system-capable-of-sensing-range-doppler-and-synthetic-aperture-radar-imaging-january-iap-2011/MIT office of the provost research highlight 2011,“2011 Lincoln Laboratory researchers, led by technical staff member Gregory Charvat, build a new radar technology system that can see through walls up to 60 feet away, creating an instantaneous picture of the activity on the other side. The system also creates a real-time video of movement behind the wall at the rate of 10.8 frames per second.”
