but it might also be a biologist for maintaining or ensuring a healthy environment, but this profession, to my thinking, is termed "environmental biologist".

I don't believe there is an exact parallel, but... the curriculum for biologo sanitario looks quite similar to that of the "human biologist"

this is also similar:

Anche se la distinzione italiana mi sembra riduttiva, credo si tratti di questo:
http://www.sage.edu/academics/biology/programs/clinicalbiolo...
un biologo che abbia un inquadramento clinico, medico.
Per me non si riferisce in modo specifico al settore pubblico, per cui non può essere public health. Si studia nella prospettiva di un'applicazione clinica, poi bisogna vedere dove si trova un impiego.

Scienze sanitarie si trova,altrimenti, normalmente all'interno di corsi di medicina o anche statistica
Dipartimento di Scienze Sanitarie Applicate e Psicocomportamentali

In realtà ero partita dallo sbocco naturale per un biologo, lavorare in un laboratorio di analisi (sarebbe stato un laboratory biologist) e mi sono accorta dopo che la domanda è presentata come scienze sociali :
tecnico sanitario di laboratorio biomedico – laboratory technician

Science and Society - realizing the potential of new therapeutic targets
Darcey Black and Brian Henry (Schering-Plough Corporation, Motherwell, UK)

In the last few years, the phrase ‘from bench to bedside’ has become familiar in the titles of scientific reviews, research papers and scientific and medical research conferences. ‘Bench to bedside’ refers to a branch of research called translational medicine (or translational biology). The apparent growing usage of this term would suggest the development of a new paradigm in research in medical research. While this is true to a great extent, the concept and practical application, as we will see, was around in the pioneering days of biochemistry.
