If I haven't contacted you by email yet, please consider submitting your manuscript to the Special Issue I'm an editor. We have many great papers confirmed, maybe yours can be too!

Thrilled to share my first paper as corresponding author with @rejoicephd.bsky.social, Tryphena Adams, and Anthony Batte! We reanalyzed Non-Human Primate malaria data in light of new insights on AKI/AKD—key findings inside! #MalariaResearch #AKI #openscience

The study section is going from April 24-29. I was gonna be anxious, but it's too long for that

Last week - one paper out - two filled the forms. Got selected for a Rising Stars Cohort. Invited to chair a session at AAI and to give a talk in the Brazilian Immunology Conference.
Not too shabby, 2025.

Microbiome-mediated modulation of immune memory to P. yoelii affects the resistance to secondary cerebral malaria challenge
Abstract. Malaria is caused by protozoan parasites in the genus Plasmodium. Over time individuals slowly develop clinical immunity to malaria, but this pro

Adding three peer reviewed accepted manuscripts (one as co-corresponding author) to my NIH application before the study section is such a good feeling!
Not sure it's gonna make a difference, but it made my day.

Huge success!
Today I taught B cell activation class using @taylorswift13 ticket scarcity (FDC) and high demand as an example.
Having a friend (TFh) to switch when you go to the restroom, bring food, is essential to stay days in line. Affinity to Swift is not enough!

All NIH study sections canceled indefinitely. This will halt science and devastate research budgets in universities.

Our brand new review on type 2 immunity in malaria with terrific colleagues Renee Tsolis and Adrian Piliponsky highlighting the roles of mast cells and basophils in orchestrating the host response to infection and parasite transmission to Anopheles mosquitoes.
The type 2 immune response in gut homeostasis and parasite transmission in malaria
Malaria predisposes to concomitant bacteremia, resulting in increased mortality risk. Previous studies indicated that malaria causes structural changes in the intestine, induces tolerogenic immune responses, inhibits neutrophil recruitment, suppresses innate synthesis of IFN-γ, dysregulates mast cells (MCs) and basophils, and induces Th2-type immune responses. These can reduce parasite control while increasing enteropathogenic dissemination. Moreover, there is growing evidence that Th2 immunity, while protecting the host from overwhelming inflammation, may also contribute to increased parasite transmission. This review explores the roles of the regulatory immune response in bacterial coinfections and parasite transmission in malaria.

In 2024 I'm thankful for moving up Self-Respect as my top value. It worked wonders, and taught me to say no.

Hard-working wasn't cutting as the top value, it was just burning me faster.

Mentoring tip - to grow is hard. A seed must break the ground to become what it's meant to be. Make sure you're having fun even in the hard things.
Try and savor any achievement. Cytometry is tough. 14 work/h but I love so much when the panel looks great.
