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. Cover Plus New Fashion Studded Rhinestone Leather Mens Slip On Casual Dress Suit Loafers shoesThe Koskella lab takes on this challenge by combining discovery-based science on plant microbiomes with hypothesis-driven experimentation. Our research examines host-microbe and microbe-microbe interactions by first identifying patterns in nature and then, in line with current theory where available,Cover Plus colorful Genuine Leather Mens Slip On Steel Toe Dress Casual Loafers shoesCover Plus New Comfort Black Alligator Print Leather Mens Slip On Casual Dress Suit Loafers shoes John White Men's Venice Slip-On Mocassin Leather Suede shoesMen's Eye Classic Derby Leather Lace-Up shoes M 45generating predictions to explicitly test in the laboratory using a combination of experimental evolution, microbial ecology approaches, Cover Plus New Comfort Black Patent Leather Mens Slip On Buckle Formal Suit Dress Loafers shoesand molecular biological techniques.
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.

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. By combining evolutionary theory on coevolution, population dynamics, and infection genetics,Nike Jordan Men's Jordan Trunner LX White Pure Platinum Training shoes 8 Men USCover Plus New Fashion White Genuine Leather Mens Lace Up Formal Dress Suit Oxford shoesIgi&Co 3101933 shoes with Laces ManDelta Plus SMASLSPNO44 S1P HRO SRC Leather Low shoes - Black, 44 (Pack of 10) I directly test the underlying assumptions and predicted outcomes of host-pathogen and microbial interactions through the lens of human health and agricultural sustainability.
My previous work was primarily focused on host – parasite coevolution; first between a smut fungus and a plant (e.g. Cover Plus 2 color Fashion Studded Suede Leather Mens Dress Slip On Cap Toe Loafers shoes), then a trematode and a snail (e.g. Cover Plus 2 color New Fashion Genuine Leather Casual Dress Mens Lace Up Oxford shoes), 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, Cover Plus 2 color Fashion Floral Leather Mens Casual Dress Lace Up Oxford shoesand Grenson Mens Formal shoes Templemeads). 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.Adidas CC ADIZERO FEATHER III Red Men Sneakers Tennis shoesT.U.K. AV8874 Tuk Men shoes Classy Grey Suede Buckle Viva Mondo Creepers A V8874 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 placeChaussure Running CC Sonic W Multicolor B34782New Dunlop Mens Acifort A252931TW Thigh Wader Gents Slip-On Boots Welly shoes.Adidas pink Big Logo Tshirt Mens Style AZ4034-Grey Size XXLAllure Men Dress shoes AL01 Fashion Tuxedo For Wedding, Prom and Formal Events With Wrinkle Free Material Brown 14 E(W) US 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.
