Engineering biological systems to specification–for example, designing a microbe to produce a cancer-fighting agent–requires a detailed mechanistic understanding of how all the parts of a cell work. Typically, this knowledge is acquired through years of painstaking work and a fair amount of trial and error. But Berkeley Lab scientists have created an Automated Recommendation Tool (ART) that adapts machine learning algorithms to the needs of synthetic biology to guide development systematically. With a limited set of training data, the algorithms are able to predict how changes in a cell’s DNA or biochemistry will affect its behavior, then make recommendations for the next engineering cycle along with probabilistic predictions for attaining the desired goal. The work was led by Hector Garcia Martin, a researcher in Berkeley Lab’s Biological Systems and Engineering (BSE) Division and Tijana Radivojevic, a BSE data scientist. In a pair of papers recently published in the journal Nature Communications, they presented the algorithm and demonstrated its capabilities.

The projects of 15 Biosciences Area scientists and engineers received funding through the FY21 Laboratory Directed Research and Development (LDRD) program.
In an opinion piece published July 19 in ACS Synthetic Biology, Hector Garcia Martin and Tijana Radivojevic of the Biosciences Area’s Biological Systems & Engineering Division collaborated with Pablo Carbonell of the Manchester Institute of Biotechnology’s SynBioChem Centre, to highlight the opportunities in a radical new approach to bioengineering that leverages the latest disruptive advances in machine learning.
Researchers from Biosciences and the Computational Research Division (CRD) have formed a new integrated Computational Biosciences Group to develop tools for addressing a range of scientific problems that cross organizational lines. Members of the group include (pictured, from left): Héctor García Martin of the Biological Systems and Engineering and the Environmental Genomics and Systems Biology Divisions (BSE/EGSB), acting group lead Kris Bouchard (BSE), Chris Mungall (EGSB), Andrew Tritt of the Computational Research Division(CRD), Oliver Rübel (CRD), and Ben Brown (EGSB). Additional members not pictured are: Aydın Buluç (CRD), Silvia Crivelli (CRD), Hans Johansen (CRD), Talita Perciano (CRD), and Peter Zwart of the Molecular Biophysics and Integrated Bioimaging Division (MBIB).
