MEET THE GROUNDLIGHT TEAM:

Leo Dirac
FOUNDER
Leo is really into machine learning, and is passionate about using it to make the world a better place. He’s been a pioneer in applying ML to solve real-world problems for over a decade. In 2012 he started using neural networks, and was one of the first deep learning engineers at Amazon, leading its application to numerous technical and business efforts including visual search, recommender systems, and multiple generations of AWS ML services from Amazon Machine Learning to SageMaker. He founded Groundlight with Avi to build the next generation of machine learning and computer vision to enable the next generation of robotics.

Jing Redman
OPERATIONS
Jing manages operations at Groundlight and keeps things running oh-so-smoothly. She is arguably the most well-traveled member of the Groundlight team, and is the only member of the team who has set foot on Antarctica (it was cold). With connections around the world forged throughout her education and career, and a skill set ranging from Strategic UX Design to Business Development, she brings a wealth of knowledge and international business practices to the team, improving both day to day operations and charting a course for Groundlight's future. In her spare time, Jing can be found trying out new dishes to cook or playing racquet sports. She is a PNW native and likes to explore the area with her dog, Dashi.

Dr. Ali Mohammad
NATURAL LANGUAGE PROCESSING
Ali Mohammad is an engineer with a doctorate in statistical learning theory and computational linguistics from MIT. He has a broad background in mathematics, science, and engineering which he enjoys applying broadly. Despite scoring top 1% on the Putnam exam, he continually undercounts how many languages he might speak. He is passionate about technology, coffee, food, and laser cutting. In his spare time, he is a jungle gym for his two kids. He's so extroverted he already wants to be your friend.

Tyler Romero
ML ENGINEER
Tyler is a seasoned ML Engineer and Scientist who received his Master’s from Stanford and worked at Microsoft and Twitter before coming to Groundlight. While at Twitter, he conceived and shipped significant ML modeling improvements to both the Home Timeline and Conversation Ranking algorithms. Earlier in life, Tyler had ambitions of becoming a mechanical engineer, and so he spent a lot of time fabricating robots and go-karts with his friends - and he still maintains an affinity for building things in the physical world. He grew up in St. Louis and lived in many parts of the US (including Michigan, Texas, NYC, and the Bay Area) prior to settling in Seattle. On the side, Tyler enjoys playing soccer, cooking/baking, making origami, keeping up with the latest ML research, and exploring the beautiful PNW.

Brandon Wada
SOFTWARE ENGINEER
Brandon graduated Harvey Mudd in chemistry, and tied his love of machine learning and physical sciences together while studying computational chemistry at Stanford. Now, he’s further honing his computer vision skills while working with customers to make Groundlight best suit their needs. His many interests makes him an easy target for nerd sniping, whether it’s regarding books, games, or especially a puzzlehunt.

Jeffrey Tappen
INTERN
Jeffrey grew up in the Pacific Northwest, so he is no stranger to Seattle where he is currently a student at the University of Washington. His primary areas of study are statistics and computer science, and his main interests are machine learning and data analysis. He has been a maker, hacker and tinkerer his whole life, so if you can convince him step away from his work for long enough to tell you what he's up to, you're bound to learn a thing or two.

Avi Geiger
FOUNDER, CEO
Avi is in it for the robots. He has a long track record of bringing barely formed ideas from concept to production and doing whatever it takes along the way, leading numerous engineering, manufacturing, and business efforts at Microsoft, Picobrew, and elsewhere. And he’s a serial founder and entrepreneur who’s always looking for new solutions to old problems. He founded Groundlight with his long-time friend Leo to corral a new world of robotic capabilities at the crossroads with a new model of perception and learning. When he’s not at the office you’ll mostly likely find him teaching at UW, tinkering on myriad esoteric projects, or driving a camper van off into the sunrise with his family.

Michael Vogelsong
CHIEF ML ENGINEER
Michael hails from Colorado by way of Amazon, where he built deep learning into search engines, robotics, and health applications. He’s fascinated with the process of learning - understanding how people and computers learn new ideas. Around the office you’ll find him building whatever needs to be done today, whether its reworking the back-end database, or launching our first public API, or telling us he just turned on a fancy new machine learning pipeline last night based on a paper published last week. When he’s not here you’ll find him somewhere outdoors - playing golf, basketball, or working through his Seattle summer bucket list. He completed one Krispy Kreme challenge and will never do that ever again.

Morgan Venable
PRODUCT
Morgan thought it was too sunny at CalTech so he came to the Northwest to lead numerous product, engineering, and business efforts for Moto Design, develop futuristic interaction technologies for Microsoft, incubate Prime Air at Amazon, and manage a portfolio of AI programs at Google. Now he’s leading our product efforts to build apparently magical computer vision to anything with a camera and an internet connection. When he’s not in the office, your best chance to find him is looking up above the cliffs in Pacifica, CA where he’s an avid paraglider pilot and probably having too much fun up there to look back down at you.

Sunil Kumar
ML ENGINEER
Sunil had just wrapped up his undergrad at Harvey Mudd when he joined Groundlight. His background in Mathematics and Computer Science led him to equal parts research and development work in NLP & CV. His ability to smoothly navigate the balance of engineering perfection and functional implementation earns him the most emojis on slack, but his gif game is a close second. When not behind a screen clearing wide swaths of the Jira board, he’s out exploring Seattle and looking for new mountains to climb or ski down.

Corey Wood
INTERN
Corey grew up in the Seattle area where he knows the summers are pretty good so he came back from Brown University to join Groundlight as an intern. At Brown, he studies computer science, and is passionate about machine learning and language processing. He also enjoys reading - he’s read almost all of Franz Kafka’s written work and collects Agatha Christie mystery novels. In his free time you might find him throwing a frisbee, playing pool, trying out a new board game, or singing along to indie folk music in the car.

Thomas Yim
INTERN
Thomas Yim was born and raised in Seattle and is coming back this summer to intern with us! He is a student at Stanford University where he is studying machine learning and systems programming. He is an avid soccer player and loves to spend his free time taking photos of concerts and sporting events for the university paper.

Dr. Paulina Varshavskaya
ROBOTICS, IMAGING & RL
Paulina has lived and studied in St. Petersburg, Budapest, Vienna, London, Cambridge MA, and Edinburgh before settling in Seattle. She finished her PhD at MIT in distributed robotics, taught at Tufts, and ran the software team at an AI life sciences company identifying rare cells in microscopy images. When not directing the science effort at Groundlight, Paulina is most likely found in the mountains, sometimes alone on an alpine ridge, sometimes with her family in a camper van.

Dr. Ted Sandler
HUMAN-IN-THE-LOOP ML
Ted Sandler received his PhD in computer science from the University of Pennsylvania's School of Engineering, working on nonlinear dimensionality reduction to train machine learning systems with less human supervision. He later joined Amazon and developed Prime Video's first machine learning recommender systems. While there, he was an early proponent of machine learning, and at Groundlight now, he is excited to make computer vision available to everyone. Ted usually wins the prize for most enthusiastic explanation of fancy math at our weekly journal club. He enjoys hiking around Seattle, and fun fact: growing up in New York, Ted was one of the first kids to attend a taping of Sesame Street!

Tom Faulhaber
SOFTWARE ENGINEER
Tom has worked as an engineer, manager, and consultant and he’s been building innovative software systems at every stop. At AWS, he was the original Principal Engineer leading the development of Amazon Sagemaker, AWS’s platform for ML. He has also built systems for massive geospatial-temporal big data, scientific visualization, video intelligence, ML-driven e-Commerce and cloud-based business intelligence. Tom has also been active in the broader tech community as a speaker, mentor, and contributor to projects such the Clojure programming language. A transplant to Seattle from the Bay Area, Tom can be found hiking or kayaking in the great outdoors of the Pacific Northwest, but he still obsessively follows the Warriors and 49ers.

Jared Randall
DESIGN
Jared is an east coast transplant to the PNW, with roots in rural Vermont. He spent a few years in the tiny state of Rhode Island to get a design degree and then headed West, where he helped build a consultancy working on Scientific, Consumer, Industrial, and Medical product development. He's excited to help bring some very fresh advances in computer vision to a broad set of users. He refuses to be pinned down on what his favorite color is, and has a woodworking hobby that leaves absolutely no room for cars in his garage.

Tim Huff
INTERN
Tim is originally from Austin, but relocated to Seattle to get involved in the tech startup scene. More recently, Tim has been pursuing two masters degrees in robotics and technology innovation from UW and Tsinghua University. Tim is fluent in Chinese, which has helped him in his studies at Tsinghua. Tim’s research at Tsinghua uses computer vision to detect defects in automotive glass. At UW, he got hands-on experience with robots including a mobile picking robot called Fetch. Tim’s team programmed Fetch to autonomously navigate around a makerspace and retrieve tools. In his free time, he enjoys cycling around Lake Washington and tinkering with radio-controlled planes. Tim is excited to bring his experience to Groundlight to develop industrial applications with the Groundlight API.
