Research FocusBiogenesis, function and engineering of the eukaryotic CO2-fixing organelle, the pyrenoid
Our laboratory seeks to advance our basic understanding of cell biology. We study the pyrenoid, a mysterious phase-separated organelle that enhances CO2 capture in nearly all eukaryotic algae. Understanding the pyrenoid is important because of its central role in our planet’s carbon cycle, because the pyrenoid embodies fundamental questions in organelle biogenesis, and because engineering a pyrenoid into land plants could dramatically increase crop yields. To accelerate progress, we are developing community resources for the unicellular green alga Chlamydomonas reinhardtii as a model system for photosynthetic organisms.

Martin Jonikas obtained a B.S. in Aerospace Engineering from the Massachusetts Institute of Technology in 2004. He completed his Ph.D. in 2009 at the University of California, San Francisco working with Jonathan Weissman, Maya Schuldiner and Peter Walter on high-throughput genetics and protein folding in the endoplasmic reticulum. In 2010 he started his laboratory at the Carnegie Institution for Science on Stanford campus. In 2016, he moved his laboratory to Princeton. He is the recipient of a 2010 Air Force Young Investigator Award, a 2015 NIH New Innovator Award, a 2016 Howard Hughes Medical Institute-Simons Foundation Faculty Scholar Award, and a 2020 Vilcek Prize for Creative Promise in Biomedical Science.
