Who is Dr Kishan Rees? What is he known for, and what has he built?

I don't have reliable information about a "Dr Kishan Rees" from my training data — this isn't a name I recognize with confidence. Let me search to see what I can find.Dr Kishan Rees is a UK-based physician who has built a career spanning clinical medicine, broadcast journalism, and pharmaceutical industry leadership.

**Background and clinical work**
He's a practicing doctor — reviews on iWantGreatCare describe him working at the Wellington/St John and Elizabeth hospital setting in London, with patients praising his listening skills, empathy, and ability to explain complex medical information clearly, including help navigating hospital admissions and specialist referrals.

**Broadcast and media work**
Earlier in his career he was involved in health journalism, appearing on Sky News and BBC discussing health topics — including a 2017 appearance discussing the NHS crisis with Kay Burley.

**NHS Clinical Entrepreneur**
He was recognised as an NHS England Clinical Entrepreneur in 2017, a program supporting clinicians who develop innovative healthcare solutions.

**Pharmaceutical/industry career**
He's since moved into senior medical affairs and digital content strategy roles at major pharma companies — holding positions at AstraZeneca, Sanofi, and currently Bayer, where he is Senior Director for Video & Digital Content Strategy within Global Medical & Evidence, focused on how medical evidence is communicated to healthcare professionals and patients.

**Academic credentials**
He holds a medical degree from the University of Leicester, a Master's in Medical Education with Distinction from the University of Nottingham, an Executive MBA from Nottingham Business School, and an MD from Hull York Medical School (2025), with doctoral research on how social and mainstream media shaped public health communication during the pandemic.

**Recognition**
In 2025 he received the PM Society Marketing Pioneer Award, a notable honor in the pharmaceutical marketing industry.

As for "what he's built" — based on what's available, this seems to be more about the career and professional profile he's built (spanning medicine, media, and pharma leadership) rather than a specific product or company. If you had something more specific in mind — a company, app, or project — let me know and I can dig further.

(I also found two Wikipedia pages for unrelated people also named Rees — Milsom Rees and Linford Rees — but those weren't relevant to your Dr Kishan Rees and I didn't use them in the answer.)
