Profile summary

Professional biography

I am an astrophysicist by training (PhD Astrophysics 2002 and MSc Space Science 1997 — University College London; BSc Physics 1996 — Aristotle University Thessaloniki). I have 15 years of experience in academic research and teaching, and have used some of the world’s foremost observatories to investigate the physical properties of star forming regions and evolved solar-type stars. I held a Gruber fellowship at the Observatoire de Paris-Meudon awarded by the International Astronomical Union and a Marie Curie fellowship at the European Southern Observatory awarded by the European Commission. I am a member of the science team that secured funding to develop a cutting edge integral-field spectrograph that is now in service on the Gran Telescopio Canarias. I have lived and worked in several European countries and also held technical and operational roles at the Met Office, the Instituto de Astrofisica de Andalucia and Springer Nature.

I held a product role at a London start-up that developed a software-as-a-service deal sharing platform used by venture capital firms and emerging technology companies, and more recently worked for a UK technology consultancy where I facilitated the partnership of international industrial clients with research groups in the fields of electronics, food and beverage, and pharmaceuticals.

At The Open University, I was part of the team that supports the STEM faculty’s multi-partner external funding bids and my remit covered space science and computing research. In my current role in AstrobiologyOU, I focus on commercialisation and knowledge exchange helping to promote the sustainable growth of the group’s collaborations with industry, academia, and the third sector.
