Jillian Fiona (Jill) Banfield (born Armidale, Australia) is a geomicrobiologist and biogeochemist whose work focuses on the fundamental relationship between microorganisms and their chemical environments. Her most noted work includes publications on how microorganisms alter their chemical and physical environments during simulated bioremediation.[1]

Early life and career[edit]

As an Australian native, Banfield’s career began at the Australian National University where she completed her bachelors and masters degrees (1978–1985). She graduated with a Ph.D in Earth and Planetary Sciences from Johns Hopkins University in 1990 under the supervision of Professor David Veblen.[2] Throughout her career, Banfield has been a professor at universities worldwide, including the University of Wisconsin–Madison (1990–2001) and The University of Tokyo (1996–1998).[3] Since 2001, she has been a researcher and professor at the University of California Berkeley. Here she heads their geomicrobiology program and works as a researcher under the Lawrence Berkeley National Laboratory. Her current research spans from field sites in Northern California to Australia and from subjects including astrobiology and genomics/geosciences.[4]

Honors and awards[edit]

Research interests[edit]

Jillian Banfield’s group research focuses on how microorganisms impact mineralogy through the connection of inorganic and biological processes. Topics included in her research are sulfide mineral dissolution, soil formation, bioremediation, and astrobiology and extremophiles. An example of her research can be seen in the article titled "Virus Population Dynamics and Acquired Virus Resistance in Natural Microbial Communities" where Banfield and Andersson explain how viruses may shape the microbial community. They rebuilt the virus and host bacterial genome sequences from the natural acidophilic biofilms. They analyzed the viruses by looking for the clustered regularly interspaced short palindromic repeats (CRISPRs) which are indicators of virus resistance. Banfield and Andersson found that massive recombination shuffles the sequence to avoid creating CRISPR spacers. They further found that with existing viruses were only new spacers. This implies that the microbial community quickly acts to promote virus resistance by rapid recombination.
