===== Mission =====

The 4DN Consortium Scientific Webinar Series is designed to promote sharing ideas and establishment of new collaborations among the consortium members. It features scientific presentations by 4DN member group. These presentations are focused on new discoveries, and new approaches and are not meant to be high-level summaries of deliverables/objectives of each project as in annual consortium meetings. Each group is strongly encouraged to present unpublished research. The PI of each member group may designate either themselves or members of their group to give the presentation.

===== Format and Instructions =====

The format of this webinar series will consist of hour-long online video conferences. Each Webinar will feature two presentations, with each presentation allocated 20’ of talk time followed by 10’ of discussion. All member groups of 4DN consortium are expected to present once in this round, although some centers may present twice given the size of their grants.

===== Presentation Assignments =====

The Webinar organization committee has discussed and come up with a schedule for presentations after February 2021. See the schedule here: [[https://docs.google.com/spreadsheets/d/122eouLgJtMoCJNKmNhygufdU1qqEy-dDomxqqyQ1TxM/edit?usp=sharing|Scientific Webinar Assignment 2021-2024]].

**The schedule is ranked by funded project and the corresponding PI's last name. While the corresponding PI is put in the presentation slot, it is up to the corresponding PI to decide who in their team is to give the talk. It is encouraged that trainees are given the chance to present. If the corresponding PI wants to switch with someone else on the list in a mutual agreement, then she/he has the responsibility to arrange it and let the Webinar organization committee know.**

**Scientific Webinar Committee: **Ana Pombo, Golnaz Vahedi, Sheng Zhong, Ting Wang, Wenbo Li, Sui Huang, Yin Shen, Taekjip Ha

**Siyuan Wang**

**Associate Professor**

**[[siyuan.wang@yale.edu|]]**

**Title: //“Sequencing-free whole genome spatial transcriptomics at molecular resolution in intact tissue”// **

Siyuan (Steven) Wang, Ph. D., is an Associate Professor of Genetics and Cell Biology at Yale School of Medicine. Research in his lab focuses on the development and application of state-of-the-art image-based omics approaches to understand the spatial organization of mammalian genome and transcriptome, and how they impact cellular states. Originally from China, Dr. Wang received a Bachelor of Science degree in Physics from Peking University in 2007. He then moved to the US and received a Ph. D. in Molecular Biology from Princeton in 2011 and later his postdoctoral training at Harvard. In 2017 he was appointed Assistant Professor by Yale University, and was promoted to the rank of Associate Professor in 2023.

**Julian Pulecio Rojas**

**Senior Scientist**

**[[pulecioj@mskcc.org|]]**

**Title: //“Functional chromatin signatures preestablish future lineage-specific enhancers in embryonic stem cells”// **

Julian is a biologist oriented to study the mechanisms that regulate cell fate and to develop lineage conversion strategies to generate clinically relevant cell types in vitro. He works as a Senior Scientist in the laboratory of Danwei Huangfu at the Memorial Sloan Kettering and is currently in the job market to start his own laboratory. His current research aims to elucidate the epigenetic factors that support cellular plasticity in pluripotent stem cells.

The Webinar Series will be on the **4th Friday of each month from 8am-9am Pacific Time, 11am-12pm Eastern Time.**
