Thomas made a huge contribution to occupational dermatology in Germany, particularly with the recognition of occupational skin diseases and latterly, occupational skin cancer and worked closely with the insurance industry.

He authored more than 620 peer-reviewed publications and book chapters in the field of dermatology, allergy and  epidemiology. He was instrumental in co-ordinating the publication of the multi-authored Guidelines on Hand Eczema for the ESCD. His many academic interests included occupational dermatology, contact dermatitis, allergy, hand eczema, atopic dermatitis, environmental dermatology, skin toxicology and in later years, skin cancer and its epidemiology, and evidence-based dermatology. He was in great demand as a speaker at conferences worldwide, enjoyed travelling all over the world and was always willing to help colleagues.

Sadly, Thomas left us far too early in March 2020 at age 67, leaving behind his Japanese wife Keiko and a young son Kento, aged 5.
