This week we have a surprise treat - a conversation with Jonathan’s twin brother, Matt. He discusses his energetic commitment to mentoring and grant-writing workshops. They share their genetics, but also a desire to “help scientists do better science” Matthew comments on the usefulness of healthy competition in scienceMatt compares the joy of running a lab to cooking in the kitchenHe loves the flexibility of science and constantly stimulated by interactions with colleagues and young scientists and new ideasMatt makes a strong argument for peer-to-peer mentoring, cascade mentoring and seizing constant casual mentoring opportunitiesHe comments on the advantages of going to a small lab for graduate school and he advises students to look carefully at the type of scientific questions, the environment of the lab and the chemistry of the PI/mentor relationshipMatt describes his pioneering Grant Proposal Success (GPS) grant-writing program and the importance of collective, grant-writing communities. Matt dissects the grant structure and tells us what funding committees are looking forHe suggests that staggering projects and having work at different stages can help to integrate life and manage the labHe mentioned these institutions :   University of Leeds, UK : https://www.leeds.ac.uk/University of Pennsylvania : https://www.upenn.edu/Children's Hospital of Philadelphia (CHOP) : https://www.chop.edu/National Institutes of Health (NIH) : https://www.nih.gov/Salk Institute for Biological Studies : https://www.salk.edu/University of California San Diego : https://ucsd.edu/To find out more about Matt visit his website or follow him on Twitter : https://twitter.com/WeitzmanLab https://www.chop.edu/doctors/weitzman-matthew-d https://pathology.med.upenn.edu/department/people/517/matthew-d-weitzman 30 Second Genetics : https://www.amazon.com/30-Second-Genetics-revolutionary-discoveries-explained/dp/1782405097 To find out more about Renaud : Twitter : https://twitter.com/LePourpreLinkedIn : https://www.linkedin.com/in/renaudpourpre/To find out more about Jonathan : Twitter : https://twitter.com/EpigenetiqueLinkedIn : https://www.linkedin.com/in/jonathanweitzman/%20To learn more about the soundtrack : Music by Amaria - Lovely Swindler https://soundcloud.com/amariamusique/ https://twitter.com/amariamusique
