Dr. Emm (Manos). Mic. Drakakis is an academic member of staff of the Department of Bioengineering at Imperial College London. 

Manos has studied Physics (1st Class Honours 4-year degree) at Aristotle University of Thessaloniki (AUT) - Macedonia - Greece, Electronic Physics and Radioelectrology                (1st Class Honours 2.5-year MPhil degree) at the same university, and earned his PhD in VLSI design under the supervision of Dr. Alison Payne from the Department of EEE-Imperial  where he also conducted EPSRC-sponsored post-doctoral research.

In the Department of Bioengineering, Manos has founded the Bioinspired VLSI Circuits and Systems Group whose research activities revolve around two axes:

a) "Circuits for Biology" (inspiration drawn by the need for innovative instrumentation as dictated by a specific biological or medical need), and

b) "Circuits from Biology" (inspiration drawn by operational, architectural and/or anatomical characteristics encountered in natural information processing systems). 

Dr. Drakakis has received: the West-Macedonian Award "Alexander the Great"(1986) for being fourth (4th) in Greece in the General Entry (Panhellenic) Examinations; during his UG years he received successive performance scholarships from the (Hellenic) Foundation of State Scholarships (IKY); during his two-year long military service (1994-1996)  at the Hellenic Army's Research & Technology Center he was awarded a Prize with Public Praise by the Ministry of Defence (1995).

Between 1996-1998 he was sponsored (one of eight PhD candidates in the world at the time) by the Micro-Electronics Research Center (MERC) of LM Ericsson -Kista -Stockholm directed by Dr. Gunnar Bjorklund.

In 2006 he received the Rector's Award for Excellence in Research at Imperial.

In 2012 he received the Lecturer of the Year Award from his Dept. and its students “for providing “real engineering” context and practice embedded in taught courses and for going the extra mile in developing new courses and materials”.

His Group have received a Live Demo Special Session Prize (IEEE International Symposium on Circuits and Systems, New Orleans, 2007) and a Finalist Award (IEEE Midwest Symposium on Circuits and Systems, Cincinnati, 2005). 

Dr.Drakakis is a member of the BIOCAS and CNNA IEEE Technical Committees, is past Associate Editor for IEEE Transactions on Circuits and Systems Part I, past Associate Editor for IEEE Transactions on Circuits and Systems Part II, past Guest Assistant Editor for IEE Electronics Letters and past Subject Editor for the International Journal of Electronics - Taylor & Francis.

Currently he acts as Associate Editor for IEEE Transactions on Biomedical Circuits and Systems.
