A high-profile CTO has left blood-sensing startup Zedsen after just six months in the role.

Dr Caroline Hargrove only joined Zedsen, a HealthTech which aims to gather blood data using sensors on the skin’s surface, in April.

She has now been appointed CTO at Ceres Power Holdings, a developer of fuel cell and electrochemical technology.

Dr Hargrove has served as a non-executive director of listed Ceres since September 2018 and will step down from the PLC board and join the executive management board when she begins the role next month.

Mark Selby, the current CTO, will move to a newly created position as chief innovation officer.

Dr Hargrove, former CTO at online doctor unicorn Babylon, previously spent 20 years working in Formula 1. After leading McLaren’s vehicle dynamics research through digital twins of the racecars, she founded McLaren Applied Technologies.

“Caroline is an engineer with huge credentials and an expansive knowledge of exploiting technology commercially,” said Ceres CEO Phil Caldwell.

“I am delighted that she has agreed to join the company as an executive. She brings unique skills and experience in leading digitalisation and managing high growth technology teams which will be invaluable for the next chapter of Ceres’ development.”

Dr Hargrove said: “Working with Phil and the team over the past three years has convinced me that Ceres has the technology, the people and the commercial opportunities to make a meaningful contribution to the global energy transition. 

“I look forward to building on the excellent platform that has been established and to contributing to the future growth and success of the business.”

Selby joined Ceres in 2006 and will step away from the full-time operational CTO role to focus his efforts on developing new and future opportunities for Ceres. 

“Mark has led tirelessly on all aspects of the strategy and delivery of Ceres’ SteelCell technology development,” added Caldwell. 

“This new role will leverage his considerable knowledge while providing the opportunity for him to focus on establishing future innovative technology.”
