Dr Tang holds an MBChB from the University of Manchester, MRCGP (Membership of the Royal College of General Practitioners), DFFP (Diploma of the Faculty of Family Planning), JCPTGP, and an MBA from the Open University Business School.

As Medical Director of Biox Medical Ltd and co-founder of MeCheck (a clinical diagnostic testing platform), he has spent the last decade working at the intersection of preventative medicine and accessible healthcare.
