Mary Lou Jepsen (born 1965) is a technical executive and inventor in the fields of display, imaging, and computer hardware. Her contributions have had worldwide adoption in head-mounted display, HDTV and projector products.
She was the co-founder and first chief technology officer of One Laptop per Child (OLPC) a non-profit that generated more than $1B in revenue and helped create $30B in revenue for its for-profit partners. Subsequently, she founded Pixel Qi in Taipei, Taiwan, focused on innovative opto-electronic architectures and the manufacturer thereof. She was a project leader at Google X, and after that an executive at Facebook / Oculus VR. Among her objectives at Facebook was leading a concerted effort to bring Virtual Reality to the next level.
She is also the founder of OpenWater, a startup working on fMRI-type imaging of the body using holographic, infrared techniques, . and a member of the Xconomists, an ad hoc team of editorial advisors for the tech news and media company, Xconomy.
Early life and education
Jepsen studied Studio Art and Electrical Engineering at Brown University. She received a Master of Science in Holography from the MIT Media Lab, and then returned to Brown to receive a Ph.D. in Optical Sciences.
Her PhD work combined theoretical coupled-wave analysis with lab work, in which she created large-scale, embossed surface-relief diffraction gratings with liquid crystal-filled grooves with high diffraction efficiency in un-polarized illumination.
She has created some of the largest ambient displays ever. In Cologne, Germany she built a holographic replica of pre-existing buildings in the city's historic district and created a holographic display encompassing a city block.
MIT Media Lab and OLPC
In 2005 Jepsen joined the faculty of the MIT Media Lab as a professor with a tenure-track position. Here she started the Nomadic Displays Group, and co-created the first holographic video system in the world in 1989, where the interference structure of the hologram was computed at video rates, and shown on her hand-made display. This system inspired a new subfield of holographic video and received numerous awards.
She simultaneously co-founded One Laptop per Child, working with Nicholas Negroponte . to start One Laptop per Child, a $100 computer, the lowest-power laptop ever made. As of 2013, millions of units have shipped to children in the developing world and revenues are beyond the billion dollar mark. There are deployments in over 50 countries and in more than 25 different languages.  For the entire first year of the effort (2005) she was the only employee of One Laptop per Child [OLPC]. By the end of 2005, she had completed the initial architecture, led the development of the first prototype , and signed up some of the world's largest manufacturers to produce the XO-1. By the end of 2007 she had led the laptop through development and into high volume mass production. At OLPC, Jepsen invented the laptop's sunlight-readable display technology and co-invented its ultra-low power management system, and transformed these inventions into high volume mass production. .
Hooked on the impact that OLPC was having using the massive factory infrastructure of the world, she left Boston to split her time between Silicon Valley and Asia.In 2008 she started a for-profit company, Pixel Qi, to commercialize some of the technologies she invented at OLPC. The firm's business was based on the concept that the screen is the most critical component of any mobile device. It aimed to deliver high performance, low-power, sunlight-readable screens for mobile devices. The long term vision of Pixel Qi was to create devices that never needed to be recharged by lowering the power consumption and using alternative power generation and battery technologies. Its screens became available in a few dozen[which?] commercial and specialized products with sunlight readability, and reduced screen power consumption (which typically accounts for about 90% of the power draw in a tablet, and 70% of the power draw on a standard cell phone.
Jepsen joined Google X in 2013. She advised and directed display and consumer electronic programs throughout Google. The Wall Street Journal reported that among her projects there she created Google Lego TV: displays composed of smaller screens that plug together like Legos to create vast, seamless images and "live walls" for wall size interaction, television, video conferencing and gaming, to virtual reality without having to wear anything on your face or body. She was also one of the first contributors in Google's "Solve for X" projects with her idea of "Imaging the Mind's Eye".
In February 2015, she joined Facebook as an executive for virtual reality.
In 2016, Jepsen founded Openwater, a firm aiming to use infrared holography to make fMRI-type imaging inside the body practical, at the price level of consumer electronics and in wearable form factors. She gave a talk at 2018 TED on the technology behind the Openwater approach.

Jepsen is married to John Patrick Conor Ryan, formerly a partner at Monitor Group. In 1995, she suffered from a pituitary gland tumor and had it removed and thus suffers from panhypopituitarism, requiring a twice-daily regimen of hormone replacement; her personal description of this and the ongoing challenges she faces was published in the New York Times.
