 scription: Biofilms are communities of microorganisms that embed themselve
 s in a matrix of self-secreted extracellular polymeric substances. The mat
 rix protects the microbial community from chemical and mechanical insults\
 , thus favoring its survival and evolutionary success. Biofilms are the pr
 imary mode of growth of bacteria and have a crucial impact in environmenta
 l\, industrial\, and medical settings. However\, there is a significant la
 ck of understanding about how the physical structure and chemical composit
 ion of biofilms determine their resistance to harsh environments. Our work
  focuses on the bio-physical drivers of biofilm assembly and the emergence
  of distinctive morphological and mechanical properties. I will showcase e
 xamples of biofilms grown under different environmental conditions\, rangi
 ng from moist surfaces to surfaces exposed to fluid flow and porous media 
 and by different bacterial species. For each case\, I will present the exp
 erimental platform we developed to investigate the specific system and the
  results we obtained. Through our research\, we discovered that the interp
 lay between biological functions and physics mechanisms controls biofilm a
 ssembly\, morphology\, and rheology\, ultimately affecting their physiolog
 ical protective function. Shedding light on this interplay can help us con
 trol biofilm development and shows the prominent role that material scienc
 e can play in developing novel antimicrobial and antifouling strategies.
