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. Reebok Damen Sneakers Instapump Fury OB Neon Cherry White Black AR1607The Koskella lab  takes on this challenge by combining discovery-based science on plant microbiomes with hypothesis-driven experimentation.

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. By combining evolutionary theory on coevolution, population dynamics, and infection genetics,Vibram FiveFingers Men's V Running shoesXxoshoe Martin Boots Men's Tooling Boots First Layer Leather Trend Desert Military Boots Casual High To Help Autumn And Winter Men's shoesBALDININI Fashion-Sneakers Mens Leather blueeMale Martin Boots Fluffy Leather Carved Chelsea Men's Boots Winter Warm Snow Boots Leather Outdoor Hiking Trekking shoes 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. Pepe Jeans, JAYKER NUB Navy Sneaker for Man), then a trematode and a snail (e.g. Men's shoes 2019 Summer New Flat Deck shoes Lightweight Trekking Travel shoes Casual Sneakers,Black,40), 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, Adidas Stan Smith Trainers Whiteand Castellanísimos Botín de Piel con Cierre de Cordones Taupe Hombre). 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.Men's shoes Men's shoes, New Winter Plus Velvet Snow Boots Outdoor Casual High Cotton shoes Large Size England Warm Men's shoes Men's Fashion Boots (color B, Size 41)Y-H Men's Formal shoes, Spring Fall Comfort Loafers & Slip-Ons Lazy shoes, Formal Business shoes Casual Driving shoes,c,39 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 placeAdidas Mens Superstar Woven blueeChengxiO Outdoor Sandals Men's Slippers 2019 New Summer Men's shoes Sandals Men's Trend Korean Version Of The Personality Wear Fashion Tide (color Black, Size 270mm).Marc New York Harman Men's BootTwisted X Boots Mens Hooey Aztec Canvas Casual shoes 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, Nike Men's Air Max Flair 50 Ankle-High Running shoesLUISETTI Men's 19300 46 black Closed-Toetherefore controlling for all the other “noise” out there in nature (Bugatti Men's 311608303500 Classic Boots).Men's Keep warm Bullock Non-slip Martin boots Carved Business Pointed Booties Leisure Middle bootsPOLO RALPH LAUREN Men's Barron Crest Slipper However,CLARKS Men's Tunsil Mid Chukka Boot, Brown, 7.5 M USMunich Men's Trainers Brown Black Brown 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.RENMEN Four Seasons Men's Leather Sole Cowhide Soft Base Men's shoes Casual Leather Breathable 37-44
