Sheryl HostlerSheryl Hosler is currently a graduate student in the biology program at Northern Illinois University, where she researches community restoration ecology in a tallgrass prairie. Sheryl is passionate about arthropods, with her main study organism currently being dung beetles. Before grad school, Sheryl spent the better part of 5 years as an environmental educator. Strongly invested in science communication and outreach, Sheryl loves to teach the public more about environmental science. To further these efforts, she is the creator and host of 2 YouTube channels, Get Messy (for kids) and The Roving Naturalist (for young adults).


21st August – Rachael Bonoan, Tufts University

Rachel BonoanHi! My name is Rachael and I am a Ph.D. candidate in the Starks Lab at Tufts University in Medford, MA. As a lab, we study behavioral ecology to understand how animals deal with environmental pressures. My research focuses on how seasonal changes in honey bee diet (i.e. flowers!) affects honey bee health and behavior.

When we go to the grocery store, we have a lot of choices. While our choices do change with season (try to find pumpkins in the summer, or berries in the winter), those choices tend to remain diverse. The “grocery store” for honey bees is our lawns, our gardens, etc., and the choices aren’t always diverse. In the early New England spring, honey bees only have dandelions or clovers to choose from. The summer brings a more diverse choice of flower foods and in the fall, the main choices are goldenrod and aster. How might honey bees change their foraging habitats to cope with the lack of choices? How could the lack of choices alter the honey bee gut microbiome? How does a lack of diet diversity affect the honey bee’s immune system?

These are just the broad questions I am interested in answering during my Ph.D. One of the first studies I did as a Ph.D. student was on honey bees drinking dirty water—you can read about what I found here. Also, check out my personal website to follow my adventures in field biology and beekeeping!

Outside of my research, I enjoy communicating science to the public and am the President of the Boston Area Beekeepers Association. I can also be found playing middle infield for the Tufts Biology Department softball team (Base Pairs), kickboxing at a nearby gym, baking (especially brownies and cookies), crawling on the ground photographing insects, or visiting my waterside hometown in Rhode Island.

14th August 2017 – Inés Dawson, University of Oxford

Ines DawsonInés is a final year interdisciplinary DPhil student at the University of Oxford. Her research, with a strong background in biological sciences, involves studying the biomechanics of insect flight, specifically how an insect’s flapping wing and body kinematics translate into the complex aerial manoeuvres performed during free flight. This combination of biology and engineering is aimed at inspiring the next generation of bio-inspired MAVs.

Apart from her research, Inés is also an award-winning science communicator in English and Spanish and runs two YouTube channels, Draw Curiosity and Inés-table, in order to make science stories interesting and internationally accessible. She is an enthusiastic and engaging educational speaker who enjoys informing and entertaining audiences of all ages and nationalities about different aspects of science.

In addition to her personal science communication work, she has also collaborated with BBC World Service, Discovery, Merck and Naukas to help put a human face on scientific research.

3rd July 2017 – Lauren Diepenbrock, North Carolina State University, Entomological Society of America

Lauren DiepenbrockI am an insect ecologist working in integrated pest management as a postdoctoral research scholar at North Carolina State University. This basically means that I study the ecology of insect pests and incorporate that into management programs to help growers produce healthy crops. At NC State, I study a challenging invasive vinegar fly, spotted wing drosophila (Drosophila suzukii), a nearly worldwide pest that impacts small fruit crops (cherry, blueberry, blackberry, raspberry, strawberry, etc.). I also manage a multi-institutional Specialty Crops Research Initiative grant working with researchers all over the United States on coordinated research addressing the management of spotted wing drosophila.

Prior to my postdoc position, I did a Master’s at Florida State University where I studied the seasonal natural history of trap-jaw ants (Odontomachus brunneus) in North Florida with Dr. Walter Tschinkel. I consider myself very fortunate for this opportunity to observe these organisms and learn about their unique behaviors. The observational skills that I learned during this work have been helpful both in my PhD and postdoctoral research.

I did my doctoral research with Dr. Deborah Finke at the University of Missouri. For my dissertation, I looked at the impacts of resources, historical land use, and invasive species on native lady beetle communities in tallgrass habitats in Missouri. Tallgrass prairie was once the predominant land cover for much of this region and has, over time, been converted to agricultural land. I wanted to understand how changes in land use and the restoration of some lands to tallgrass prairie impacted insect communities, and I chose to focus on lady beetles because of recent studies documenting negative impacts of invasive lady beetles (e.g. Harmonia axyridis, Coccinella septempunctata) on native species. One of our major findings is that grasslands (native or agricultural) are really important for promoting the persistence of native lady beetles.

During my week on BioTweeps, I’ll talk about natural history, insect ecology, beneficial and pest insects, integrated pest management, and ongoing research.  There will likely be random cat pictures, discussion of experiences from grad school and beyond, how to make the most out of interesting opportunities along the way, the hunt for a faculty position… and anything else that is of interest at the time. I’m happy to answer whatever insect questions that I can and refer those that I cannot answer to people who can.

22nd May 2017 – Seth Barribeau, University of Liverpool

I’m an evolutionary ecologist who largely works on understanding how insects are able to do complicated things with what is generally considered a ‘simple’ immune system. Spoiler: it’s not that simple. I am fond of most animals, with the noticeable exceptions of ostriches (they have cruel, dead, eyes) and locusts (a childhood incident). I started out studying the what predisposes tadpoles to infection as a graduate student in New Zealand, and after a brief stint catching snakes, teaching English, and proof reading medical articles in Japan, moved on to studying aphids and fungus-growing ants at Emory University, and then bumblebees at the ETH in Zürich. After studying and postdoc-ing in several countries I recently started a position as the lecturer for eco-immunology at the Institute of Integrative Biology at the University of Liverpool.
My recent research has explored why aphids have a pretty rubbish immune system, why the costs of mounting an immune response differ among individuals, how diet influences the expression of immunity, how bumblebees respond differently to different genotypes of a common parasite, what makes immune memory, what does sociality do to the evolution of the immune system, and, most importantly, was Marvin Gaye right? Is there such a thing as sexual healing?

7th November 2016 – Julia Koricheva, Royal Holloway University of London

julia-korichevaHi everyone! I am a Professor of Ecology at Royal Holloway University of London, UK. I have started my scientific career in Russia (when it was still part of the Soviet Union) with BSc in Zoology/Entomology from St Petersburg State University. I did my PhD in Finland, at University of Turku in Prof. Erkki Haukioja’s research group. My PhD project was on effects of air pollution on interactions between birch trees and insect herbivores feeding on them.

My first postdoc was at University of Zurich in Switzerland in EU Project BIODEPTH which studied effects of grassland diversity on ecosystem functioning. Involvement in this project made me interested in biodiversity-ecosystem functioning research, and, after returning back to Finland, I have established a large-scale long-term Satakunta forest diversity experiment. It was one of the first forest diversity experiments initiated specifically to study effects of tree species and genetic diversity on forest ecosystem services and processes, and I still return to Finland every summer to conduct field work there.

My second postdoc at Swedish Agricultural University with Prof. Stig Larsson introduced me to meta-analysis and research synthesis. I became a big fan of meta-analytic approach and has been using it ever since to combine results of studies on various research topics in basic and applied ecology. I have also been teaching courses on meta-analysis in ecology for early career researchers around the world from Finland to Mexico, Brazil and Tasmania.

For the last 12 years I have been working at Royal Holloway where my research is focussing on three main areas: research synthesis and meta-analysis in ecology, forest diversity and ecosystem functioning, and plant-herbivore interactions. I am also involved in teaching a variety of field- and lab- based ecology courses at RHUL.

1st August 2016 – Martin Johnsson, Linköping University, Sweden

Martin JohnssonI am a postdoctoral researcher at Linköping University in Sweden. I am interested in the genetic basis of quantitative traits, in applying genomic tools to quantitative genetics, and in chicken domestication. That is, I use computers and pipettes to figure out what genes and genetic variants make domestic chickens different from wild chickens, and feral chickens different from both of them. I am also involved a bit with fruit fly and dog genetics.

Domestic animals have changed a lot from to their wild cousins. Just compare a domestic layer, broiler or fancy breed chicken to the Red Junglefowl, or a pug to a wolf. These evolutionary changes happened during the last 10 000 years — a few thousand less for the chicken, and a few more for the dog. Thus, domestic animals are great for studying genetic differences in traits. Populations and breeds are genetically different from each other, and from wild populations. Also, Red Junglefowl are still here, and can interbreed with domestic chickens, so that we can make crosses between them.

In our group, we work with a intercross of layer chickens and Red Junglefowl. Each individual carries a different mixture of domestic and Red Junglefowl variants. We then measure all kinds of traits that vary in the intercross population. For instance, we record body mass, reactions in different behavioural tests, gene expression in different tissues, and so on. Then we type them for a set of genetic markers, and find the markers that are associated with differences in traits. Thus, we build up a map of the genetic basis of chicken domestication.

During this week I will tweet about all of this. There will also be notes from the everyday business of research. At the time of writing this bio, I am not sure what I will be working on during the week, but laboratory selfies and an inordinate fondness for chicken combs is to be expected. See you on Twitter!
