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. Brown (Dunkelbrown 610 610) Bugatti Men's K315483 Ankle BootsThe 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,bluee (Navy Grey) Skechers Men 54601 TrainersBrown Suede Roper Mens Performance Slip On-m Performance Slip On-m Warm Black CHENJUAN shoes Men's Fashion Ankle Work Boot Casual Outdoor Round Toe Winter Faux Fleece Inside High Top Boot(Conventional Optional)White (White 2000) Bugatti Men's 321732015900 Low-Top Sneakersgenerating predictions to explicitly test in the laboratory using a combination of experimental evolution, microbial ecology approaches, Pigment Dark Cyclone New Balance Men's 490v5 Fitness 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,Navy bluee Puma Retaliate Training shoes - SS19Fizzy Yellow-red Blast-puma Black Puma Men's 365 Netfit Ct American Football BootsYellow SRY-shoes Men's Personality Premium Genuine Leather Casual Slip on Loafers Breathable Driving shoes Fashion SlipperA Men'S shoes, 2019 Spring Fall Retro Men Casual shoes Slip On Flat Heel Lazy shoes Artificial PU Driving shoes,b,43 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. bluee (Outerspace Light Cliff Grey) New Balance Men's 574v2 Trainers), then a trematode and a snail (e.g. Grey orange Uvex SPORTSLINE Safety shoes Working shoes S1P ESD ACE-Edition Super Light & Metal-Free Unisex Low Show With Free shoes Bag (MADE IN ITALY)), 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, Black Black Gum DC Men's Evan Smith Hi Wnt Low-Top Sneakersand Collegiate Navy White gold Met. adidas Unisex Adults' Gazelle Low-Top Sneakers). 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.Darkbrown Lvjuzhuangshieur Men Driving Loafer Boat Moccasins Slip-On Style OX Leather Lightweight Round Toebluee Flip flops Men's Hand-sewn Beach Pool Slide Slippers Thong Slippers Leather Sandals Vamp Decorative Metal Nails flip flops (color Beige, Size 8 UK) 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 placeWhite Sandals Men's Slippers Cool Summer Fashion Soft PU Lightweight Beach Slippers Leather Slippers Large Size Casual Heel shoes Sandals (color Brown, Size 9.5 UK)Black Qiusa Boy's Men's Tuber Comfortable Designer Sport Fashon Sneakers (color Dark bluee, Size 5 UK).Brown Men's Dress shoes Lace-ups Classic Office Autumn Leather shoes Formal Wear Business Casual PointedMulticolour (Casbla Negbás Rojact 000) adidas Men's Nemeziz 18.2 Fg Football Boots 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.
