In September the lab welcomes two new group member, Letitia Ho '19 and Allan Gao '19.

In September  Barrett, Irene, Sayed and Deondre presented their research at Swarthmore Sigma Xi poster session at Swarthmore as well as at Undergraduate Science Research Symposium at Haverford.

In August Liliya, Barrett, Irene, Sayed and Deondre went to the 252nd ACS National meeting. Liliya and Barrett gave oral presentations while Sayed, Irene, and Deondre presented posters. 

In July the whole lab (Liliya, Amber, Barrett, Deondre, and Sayed) went to Louisville to meet the lab of Brad Chaires. We had two  exciting and wonderful days of intense research collaborations. We learned how to run AUC, ITC, Stop-flow, and computer modeling, and got excellent data. Read more about our Louisville trip here.

Liliya, Amber, Barrett, Deondre, and Sayed began ten weeks of summer research in the Yatsunyk lab on May 31.

Our lab attended the third Philadelphia Inorganic Colloquium (PIC-3) on March 19 at the U. of Delaware (  Thomas Ruan presented a poster titled: "Interactions Between G-Quadruplex DNA and Porphyrin Ligands"; Alice, Sayed, and Barrett presented their poster titled: "Interactions Between Non-canonical DNA and Ligands".

Congratulation to Liliya on her recent publication of "Blending quadruplexes and Bordeaux: a Grand Cru! The 5th International Meeting on Quadruplex Nucleic Acids, Bordeaux (France)" in Cell Chemical Biology (2016),

Navin received a travel grant from French Government for his trip to Bordeaux, France this summer. Congratulations Navin!

Michelle was awarded the prestigious SURF (summer research fellowship) award from the American Chemical Society, Division of Organic Chemistry. Congratulations Michelle!

Steven got accepted to every graduate school he applied to and finally decided on Stanford!!!! Congratulations Steven!

Navin and Michelle attended the Thomas Jefferson University Sigma Xi Research day in Philadelphia, PA, on April 17, 2013. Michelle presented a poster entitled Synthesis and preliminiary characterization of polyamide derivatives of protoporphyrin-IX and mesoporphyrin-IX, and Navin presented a poster called N-methyl mesoporphyrin-IX as a sensitive reporter of strand orientation in guanine quadruplexes.

Jack received NSF Graduate Fellowship and NDSEG Graduate Fellowship from the Department of Defense in March 2013. Now he has to choose.


2012 Archives

Our lab attended Swarthmore Sigma Xi poster session on October 26-27, 2012, and presented three posters focused on our summer research.

Our lab presented posters at the Haverford Undergraduate Research Symposium on September 22, 2012. Steven and Michelle gave an oral presentation regarding their research on the crystal structure of the NMM-Tel22 complex and the synthesis of novel amide porphyrin derivatives to students and faculty at the event.

Congratulations to Liliya on her publication in Biochemie:

Alessandro d'Urso (Ale) of the University of Catania visited the Yatsunyk lab on September 15, 2012 and presented his research on inducing chirality in porphyrin-DNA complexes. Lab members also gave short presentations and discussed exciting collaborations with Ale's lab.

Our lab attended the 244th American Chemical Society (ACS) National Meeting in Philadelphia, PA, on August 19 - 23, 2012. Vienna and Navin presented a poster titled "Investigation of the Interaction between DNA and Stabilizing Metallic Compounds" and Steven, Michelle, and Jack presented "Structural aspects of the interaction between human telomeric G-quadruplexes and N-methyl-mesoporphyrin IX."

Farewell to Jack, who just graduated with high honors. He is on his way to Harvard, where he will start as a PhD student in the department of Chemistry and Chemical Biology. Good luck!

We welcome Michelle, who joined our lab in summer 2012.

Congratulations to Navin who was one of the winners of Sigma Xi Student Research Day Poster Competition at the Thomas Jefferson University in Spring 2012. Navin presented poster titled "Investigating the Interactions between DNA and a Platinum Metalloporphyrin".

Our lab welcomes Vienna, Navin and Cole who joined the lab this spring.

Congratulation to Jack and Steven, their paper is now published in Nucleic Acids Rsearch:
