Yet another project that was started by a summer high school student (Rachel Xu).

Welcome Abdullah Mahmoud, senior from Central High School working together with Jacob on analyzing the many microscopy movies taken at the Archaeal Cell Biology workshop (see below).

Welcome Nadira Thompson, joining us from CCP to learn more about microbiology research.

July and August 2024

After presenting at meetings, Priyanka took off to Woods Hole to use what she’d learned as a student last year as a teaching assistant in the Microbial Diversity course, while Yirui and Jacob attended the Archaeal Cell Biology workshop at UCSF lead by Arthur Charles and Dyche Mullins and obtained amazing microscopy data.

June 2024

Yirui and Priyanka gave oral presentations, while Marco presented a poster – unknowingly to former ASM president Dr. Steve Finkel 🙂 – at the ASM Microbe meeting in Atlanta

Jacob presented his work at the EMBO Archaea Molecular Biology meeting in France.

 

May 2024

Our latest paper titled “Involvement of ArlI, ArlJ, and CirA in archaeal type IV pilin-mediated motility regulation” is out now in the Journal of Bacteriology! Congratulations to Priyanka and Marco for spearheading this project! In this study, we discuss how certain residues in the archaella proteins ArlI and ArlJ could be contributing to motility regulation and also show that CirA is involved in transcriptional regulation of these archaella proteins. Check out the whole article here!

 

 

A big congratulations to Jacob for passing his preliminary exams and becoming a PhD Candidate! AND we are so so happy to officially welcome Eve to the lab! So happy to have such an amazing team in the Pohlschroder Lab!

 

 

 

 

 

 

We also want to congratulate Jacob for receiving the NSF Graduate Research Fellowship Program (GRFP)!! This is a fantastic honor and we are so proud of Jacob for his accomplishments!

December 2023

Happy holidays! From the Pohlschroder Lab

November 2023

We celebrated two birthdays this month! Jacob started off the month with his birthday and Priyanka rounded out the month with hers! (November truly is a great month for birthdays)

 

 

 

 

 

 

We also attended the Annual Biomedical Research Conference for Minoritized Scientists (ABRCMS) in Phoenix! Mecky and Marco went to represent the lab. Marco made good use of his Travel Award. He also won a poster award for the Microbiology category!!!!! Congratulations Marco!!!! We are so so proud of Marco and his achievements in the Pohlschroder Lab!

 

 

Marco is posing with two other students from the PennFERBS program, which was founded by Mecky. This program, the First Exposure to Research in the Biological Sciences, is a fellowship program for high-achieving undergraduate students. No wonder we have three of those students shown winning a poster prize from ABRCMS!

 

 

 

 

 

 

 

 

 

October 2023

 

 

 

Congratulations Priyanka, for winning the Microbiology, Virology and Parasitology Poster Award!!!!!!!

 

The graduate students in the lab all went to the symposium to show Priyanka support at the poster session! Pictured left to right we have Jacob, Priyanka, Eve, and Yirui.

 

 

 

 

 

 

 

Priyanka was also given the opportunity to speak at the 2023 Chemistry-Biology Interface Symposium! Her project is at a unique intersection between microbiology and chemistry and she was able to share her research story with others interested in chemistry and biology!

 

 

 

 

 

 

 

 

September 2023

We started the school year with a new rotation student. Everlyne (Eve) Mutua is a first year student in the Biology department. She will be working on characterizing a couple H. volcanii genes in relation to cell shape and biofilm formation. Welcome Eve! We’re so excited to have you! We even came up with a lab name for you: AutoclEve!

This month Priyanka gave a talk at the Prokaryotic Seminar Series! Her talk was titled “Cell-cell Signaling in Archaea: How Haloferax volcanii Talk to Each Other“. It was her first official talk, and she killed it!

 

 

To celebrate Priyanka’s talk, Eve rotating in the lab, and Yirui’s last evening in Philly before she went on vacation, the graduate students went out to dinner at Kilimandjaro Restaurant in West Philly. Pictured here we have from left to right: Yirui, Eve, Jacob, Priyanka

 

 

 

 

 

 

We are also SO PROUD of our undergraduate Marco!! His poster got accepted at the Annual Biomedical Research Conference for Minoritized Scientists (ABRCMS) in Phoenix this year! His poster is titled, “Suppressors of Motility Mutants in Archaeal Flagella Biosynthesis Components Reveal Novel Motility Regulation”. And not only that, but Marco ALSO got awarded a full travel grant that will cover conference registration, housing from November 15-19, and airfare from Philadelphia to Phoenix. You’re going to have a blast at this conference Marco!!

We also took this picture for funsies because all the students were in the office one day, and it wasn’t even during lab meeting day!

 

 

From left to right, front row we have Marco, Priyanka and Felicitas on the computer. In the back row we have Yirui, Eve, and Jacob on the computer.

 

 

 

 

 

 

 

Summer 2023

Very busy and exciting summer in the Pohlschröder lab!

 

First, Jacob mentored two high school students from the Penn LENS (Penn Laboratory Experiences in Natural Sciences) program. Pictured we have Sophia on the left inoculating H. volcanii mutant strains. On the right we have Shalaya streaking out H. volcanii onto a motility plate to find mutant strains based on swimming motility phenotype. Sophia and Shalaya’s work helped Jacob’s project and the lab advance their understanding of H. volcanii motility. This goes to show that it’s never too early to start doing cool science!

 

 

 

Marco was able to explore different types of research beyond that of the Pohlschröder lab, specifically in the area of vaccine research. He spent the summer at the Daniel Kulp Lab at the Wistar Institute. He learned many different assays, such as ELISA, and different lab techniques, such as mammalian cell culture. Marco met graduate students from other programs and learned about research and career options to pursue after undergrad. It was a great experience for him and Marco is excited to bring what he learned from the summer back to the Pohlschröder lab during the school year!

 

 

Meanwhile, Priyanka spent her summer at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts. She was taking the Microbial Diversity course, a 6.5 week intensive course for scientists at all stages to learn more about how to culture and analyze the different kinds of microbes that live all around us. She learned new and important techniques, especially in bioinformatics, that she can bring back to the Pohlschröder lab. Priyanka also formed a strong connection with the other scientists that she met there and is growing her professional network in the microbiology field. In these pictures, we have Priyanka posing in front of Eel Pond right outside her dormitory, streaking out a plate in the MBL lab, and giving her final presentation at the end of the course on a species of agar-degrading bacteria that she isolated.

 

 

 

 

 

 

 

 

 

Yirui and Mecky also went on a trip during the summer.

They attended a Gordon Research Conference in West Dover, Vermont. It was the Archaea: Ecology, Metabolism, and Molecular Biology conference, and this year’s focus was on The Root and Branch of Discover: Lessons on Life from the Archaea. The conference was in a beautiful location, as can be seen from the pictures of Yirui posing in front of the scenery. Yirui presented a poster on H. volcanii lipoprotein biosynthesis and did a great job with it. Also, Mecky and Yirui both met many new and old faces in the archaea field! They even took a photo with former lab members Stefan and Farid. Everyone at the conference posed for a fun group photo!

 

 

 

 

 

 

 

May 2023

Graduation Season! Heather graduated with her PhD in Biology while Cris graduated with his Bachelor’s degree!

Here’s Cris and Heather with their graduation swag as newly minted alumni of the University of Pennsylvania!

February 2021

The first Archaea Power Hour was fantastic – thanks Farid Abdul-Halim and Michiyah Collins for co-chairing this inaugural meeting with nearly 120 scientists interested in Archaea Biology from across the Americas coming together to hear three amazing talks and to network! Get more archaea news @archaea_power. Thanks Alex Bisson for setting this up and for working with great students to design the archaea webpage.

January 2021

More than three decades ago, the haloarchaeal S-layer glycoprotein was the first glycoprotein identified in any prokaryote and remained one of just a few archaeal glycoproteins until now. Check out Stefan’s work defining the most extensive archaeal glycoproteome in his article “Glycoproteomics of Haloferax volcanii reveals an extensive glycoproteome and concurrence of different N-glycosylation pathways” on bioRxiv. Thanks Friedhelm Pfeiffer for yet another wonderful collaboration!

 

Michiyah Collins, Farid Abdul-Halim and I are excited to be part of the organizing committee of the “Archaea Power Hour“, a monthly meeting that gives students, postdocs and research scientists the chance to present their work and interact in a very informal way. Our goal is to strengthen, grow and diversify the Archaea community across the Americas!  Join us on February 24th at 1pm for our first meeting!

We welcome sophomore Keya Patel, who’s also in the Biology Master’s submatriculation program to our lab and are excited to have Zuha and Taylor returning to the lab in person! We even had President Gutman attend our first lab meeting 🙂 Farid’s already published a first-author Methanogen paper in the Costa lab but his H. volcanii work still is being published – see Microbiology research article describing a collaboration with the Duggin lab at the University of Technology in Sydney. Why does H. volcanii only make rods in early log phase and how does it switch to disks? Stay tuned for the answers – we, together with some great H. volcanii groups across the Globe are trying to understand this cool morphological phenomenon. December 2020

The year ended beautifully thanks to amazing work from literally everyone in the lab – check out the three papers that were published in December!  

1. Simi’s screen and Michiyah’s selection for hypermotile H. volcanii tn-mutants and the characterization of the “winners of the race” was published in Genes. This work would have not been possible without great work of all the co-authors including our collaborators, Mike Dyall-Smith and Friedhelm Pfeiffer – thanks everyone!

2. Fantastic collaboration with the Hippler lab at the University of Muenster – check out the Bioinformatics publication “SugarPy facilitates the universal, discovery-driven analysis of intact glycopeptides“. Congrats, Stefan!

3. “Haloferax volcanii Immersed Liquid Biofilms Develop Independently of Known Biofilm Machineries and Exhibit Rapid Honeycomb Pattern Formation“, that also includes three undergraduate students from the Biol376 Microbial Diversity and Pathogenesis lab course  is now published in mSphere! Oh, and let me not forget – check out Taylor’s amazing performance in the Penn Dance Group (if you don’t have time to watch all of the Glee Club/Dance collaboration, go to 15.5 min).

October 2021

Welcome to the lab Criston Young! Cris, who is part of the inaugural Penn Freshmen Exposure to Research in Biological Science (PennFERBS) cohort, will work with Heather to learn more about the liquid biofilms formation and dispersal. We look forward to working with you, Cris! Also, can’t wait to hear you perform in the Penn Band post-COVID!!!!!

September 2020 Welcome Dina Issakova, first year Biology graduate student, who is rotating in the lab this semester working with Stefan as well as Michiyah who, finally after six months is allowed back into the lab. We are excited that you can finish your exciting project on H. volcanii hyper motile mutants before graduating!

July 2020

Stefan Schulze mentored two amazing students from Carver Engineering and Science High school, Morgan Bryson and Sultanah Harper who were part of the LENS program. While we only got to know each other online this summer, we are hoping to meet you in in person to show you or lab very soon!!!!

Stefan’s recently published work on the Archaeal Proteome Project (see below) as well as his discovery and subsequent characterization of rapid liquid biofilm honeycomb pattern formation in collaborations with Heather Schiller was featured in PennToday. The manuscript describing latter work was also submitted to BioRxiv. Four undergraduate students contributed to this story and Theopy Rados from the Bisson lab at Brandeis University provided this beautiful Movie. June 2020

Our Archaeal Proteome Project (ArcPP), an international collaboration between 5 laboratories across 3 continents was just published in Nature Communications. The idea for this project was to more efficiently use existing proteomics data by combining not only resources but also expert knowledge across different fields of biology, in order to gain a deeper understanding of archaeal cell biology. Thanks and congratulations to Stefan Schulze, the postdoc in the lab who spearheaded this project, and collaborators who shared large amounts of proteome data, provided invaluable insight and carried out experiments. After demonstrating the usefulness of our approach, we made our results available in a web-database (https://archaealproteomeproject.org/). We are eager to work together with more laboratories in order to extend our analyses to other archaeal species or even bacteria, harvesting the synergistic effects of a broad scientific community.

Heather, congratulations for passing your Prelims during a very difficult period and while writing a manuscript that was only tangentially related to your prelim proposal!

Congratulations Taylor for graduating from Carver High School of Engineering and Science and for receiving the “Linda H Ahmed Award” for being an exceptional female student in the STEM fields – see you in the Fall!!!!

Sending off Georgio Legerme to Med School at the University of Florida, Gainesville and Ronald Rodriguez to Grad School at Berkeley was a bittersweet event.

Laboratory Experiences in the Natural Sciences (LENS) students Tamera Stanley from George Washington Carver Engineering and Science High School spent the summer in the lab and screened nearly 4000 mutants for a motility defect. Her work was featured in the Penn News and she presented her mutants during the LENS poster session.
