There are somewhere upwards of 1030 microbial cells living on this planet. That is a thousand billion billion times as many as humans. While pretty much every organism we can see either relies on photosynthesis (plants and algae) or respiration of oxygen (animals), microbes have mastered a huge variety of different forms of metabolisms.
There are microbes utilizing iron, manganese, sulphate, sulphite, nitrate, nitrite and various other oxidized compounds as alternatives to oxygen in respiration, the deep ocean is home to bacteria and archaea consuming ammonia, some use oxygen others nitrite, microbes are the only organisms that can use the nitrogen gas that makes up 80% of the air we breathe, there are microbes oxidizing highly toxic hydrogen sulphide and heavy metal compounds, microbes degrade the oil that is spilled in the seas by catastrophic events, there are bacteria and archaea producing ethanol, butanol, butane, methane, hydrogen and other forms of biofuel and there are plenty of ways microbes ferment substrates such as sugars, that give us beer, yogurt, sauerkraut and other delicious foods.
Often human interests, like the efficient production of biofuels for example, do not readily align with the interest of microbes, which at the very basic level would be survival and reproduction. So in order to make use of the vast potential of the global microbiome, I seek to understand how microbes interact with each other, what governs the assembly of different microbes in to communities of microbes and how can communities be designed in ways that allow the control of conversion reactions to get from a certain substrate to a desired product.
I currently hold a position as Post-Doctoral Research Associate at the University of Warwick in the laboratory of Prof. Orkun S. Soyer. I perform experiment both in the computer where I can test concepts to a high degree of abstraction and in the laboratory, where the artificial construction of microbial communities helps me develop hypothesis and concepts about the way these systems function.
