The future of sustainable human health and agriculture rests on our ability to view microbial evolution as part of the solution rather than the problem.

We focus primarily on how plant-microbiome, plant-pathogen, and bacteria-phage interactions occur, both as model systems for understanding fundamental principles and with the aim of leveraging these findings for design of novel disease management strategies.

A brief introduction to the lab and our recent research:

I am an evolutionary ecologist interested in how species interactions influence genetic diversity within populations, diversity between populations, and species diversity at the community level.

My previous work was primarily focused on host – parasite coevolution; first between a smut fungus and a plant (e.g. @Sandals Hand Woven Straw, Men'S And Women'S Towed Flip Flops), then a trematode and a snail (e.g. SOLE CRAFTED Dinley Boots Brown), and most recently between bacteriophage viruses and the bacteria they infect, which are themselves parasites of plants (e.g. if phages are locally adapted to bacteria, Men's sandals sandals men students youth beach shoes slippersand G FORCE BLACK size 3 UK). The types of fundamental questions I’ve address are:

1) How do pathogens/parasites adapt to better infect their hosts? And at what scale / speed are they capable of adapting?

2) How do hosts respond to this adaptation (i.e. coevolve) and become more resistant to their local pathogens/parasites?

3) Can antagonistic coevolution lead to increased diversity? For example, do pathogens/parasites preferentially target common hosts (i.e. the hosts that are the most fit) and therefore impose a rare-host advantage?

and 4) Does this coevolution among hosts and parasites matter to human health, agriculture, and conservation? Can we use our understanding about when and how pathogens and commensals evolve to design better treatments and to predict and prevent the spread of diseases?

So far, the body of evidence produced by the scientific community over decades of work suggests that parasites can evolve rapidly and specifically to infect their hosts, but that this doesn’t always mean they get more harmful or even better at infecting.Original Penguin Men's Carlin Walking shoes, Olive, 13 D USMinnetonka Men's Classic Fringe Ankle Boots There is also clear evidence that hosts respond by evolving increased resistance, and that this often comes at a cost such as decreased growth or reproduction. This ongoing coevolution, in which neither parasite nor host is winning the battle has been called ‘Red Queen’ dynamics, based on the idea from “Alice Through the Looking Glass” that you have to run as fast as you can just to stay in the same placeMen'S Leather shoes, Spring Fall Comfortable Loafers shoes Fashion Loafers & Slip-One Soft Driving shoes Lightweight Walking shoes Round Toe shoesFila Men's Original Fitness 1vf80172-150 Low-Top Sneakers.Hhgold sportsOutdoor shoes hiking shoes anti-skid wear-resistant sports hiking shoes (color Khaki, Size 43)DIESEL Men's Magnete Exposure I Low Sneaker At last these ideas are beginning to be incorporated into the design and use of drug treatments (sometimes referred to as Darwinian Medicine) and used to build predictive models of disease spread in our increasingly-connected world. My work has taken advantage of a very powerful approach to address these questions by experimentally evolving hosts and parasites in the laboratory, TYX-SS Men'S Office Business Casual Oxford shoes Black Brown 38-46Outdoor Sports shoes, Breathable Sports, Casual Men's shoes, Men's Mesh shoes,Brown,43therefore controlling for all the other “noise” out there in nature (QAR Black Men's Summer Slippers Fashion Non-slip Outdoor Breathable Slippers Casual Slippers flip flop (color BLACK, Size 40)).XINGUANG Men's Safety shoes Steel Toe Work Sneakers Breathable Climbing shoesSupra Men's Stacks II Vulc Trainers Brown (Demitasse Tan 272) 7 UK However,Toffeln Ultra Lite 0600 - NavyMil-Tec Tropical Boots Cordura Coyote I always try to go back to nature’s microcosm to find out whether what holds true in the lab can be used to explain what we see in the real world.LOVDRAM Men'S shoes Autumn And Winter Fashion High To Help Snow Boots Large Size Cotton shoes Non-Slip Men'S shoes
