When the Princeton University Women's Hockey team takes to the ice, each player's ice skate blades will be etched with her name and number.
Two members of the Craig Arnold Lab, Shu Hayashi and Ankit Das, in Princeton MAE, used a laser in their lab to do the etching.
This collaboration came via a connection between Prof. Mikko Haataja and Prof. Arnold, who are both in the Princeton Materials Institute (PMI) and Princeton MAE. Mikko is a professor as well as a Princeton University Athletics, Princeton Tigers Fellow for the team.
In this video, two members of the hockey team, Katherine Khramtsov ‘26 (Civil and Environmental Engineering) and Ani Kozak ‘27 (MAE major) use their newly-etched blades on the Baker Rink ice.

Jason Aramburu is the founder and CEO of Edyn, which produces a “smart” sensor system for agriculture and gardening that wirelessly tracks soil moisture and fertility. The technology allows a farmer or gardener to monitor plants and crops on an iPhone and thereby manage natural resources more efficiently. Aramburu is also the founder of re:char, which specializes in technology that helps small farmers in East Africa boost their crop yield and (and simultaneously) fight climate change.
Although Edyn is an engineering-focused company, Aramburu says that the company culture is different from that of a traditional Silicon Valley startup. “We’re creating a company culture that is laid-back and focuses on innovation but it is innovation with a social and environmental benefit,” he says. “We’re not trying to create the next Facebook or Instagram. We’re trying to create something that can meaningfully impact how people grow food, and how we use our resources in the world.”
Aramburu is one of Forbes Magazines 30 under 30 Social Entrepreneurs, an Ashoka Fellow, a 2009 Pop!Tech Social Innovation Fellow, a 2010 Echoing Green Fellow and a grantee of the Bill and Melinda Gates Foundation. He is also one of Business Weeks Top 25 Social Entrepreneurs in America. After studying ecology and evolutionary biology at Princeton University, Aramburu worked for several years on projects in Panama’s rainforests and with farmers in Africa. He graduated from Princeton University in 2007.
