ACS AMA Hi Reddit! My name is Mallory Hinks. I recently defended my Ph.D. in Atmospheric Chemistry at University of California, Irvine. For the last 5 years as a graduate student, I have worked for Professor Sergey Nizkorodov (http://aerosol.chem.uci.edu/). My work has been focused on understanding the effects of environmental conditions on the chemical and physical properties of atmospheric aerosols and how they interact with sunlight in the atmosphere. If you want a little more background, here is a video about aerosols and my research to give you a basic overview: https://youtu.be/F-UW8oMiNng While in graduate school, I developed a passion for science communication. I entered and won multiple science communication competitions including the UCI Grad Slam competition and the ACS ChemChamps competition. Following those experiences, I expanded my extracurricular activities to include more science communication opportunities. As a Science Communication Fellow for the Loh Down on Science radio show (http://www.lohdownonscience.org/), I wrote scripts for 90 second radio segments that aired on NPR. As a Communication Consultant for the UCI Graduate Resource Center, I advised students on their presentations in one-on-one meetings. I hope that I can help inspire scientists at all levels to develop an interest in science communication! I’m looking forward to answering your questions about atmospheric chemistry, science communication or about life as a graduate student! I will be back at 12:00p EDT (9a PDT, 4p UTC) to start answering your questions. EDIT: Thank you for all of your questions! This was harder than I thought it would be! I’ve got to sign off now!

The mods of /r/philosophy are pleased to announce an upcoming AMA by Barry Lam, Associate Professor of Philosophy at Vassar College and the Executive Producer and Host of philosophy podcast Hi-Phi Nation. Barry will be joining us on Monday June 5th at 12PM EST to discuss his philosophy, podcasts and everything in between with a live AMA. Hear it from him: Barry Lam I am Barry Lam, Associate Professor of Philosophy at Vassar College and the Executive Producer and Host of the Hi-Phi Nation podcast, the first story-driven documentary-style show about philosophy. I just completed production and release of the first season of Hi-Phi Nation as Humanities Writ-Large fellow at Duke University, where the first season covered stories and philosophy ranging from the possibilities of posthumous harm, the morality of war, the referent of religious terms in Christianity and Islam, the philosophy of music, the replication crisis in the statistical sciences, philosophy of gender, Kuhn and scientific realism, and the philosophy of love. I would be happy to talk about any of the substantive issues that arose from these episodes, as well as discuss any issues concerning doing philosophy in a story-driven way. Here are a few select episodes on Soundcloud: Episode 1: The Wishes of the Dead Episode 3: The Morality of War Episode 4: The Name of God Episode 7: Hackademics II (Epistemology of Replication Crisis) Some interviews and discussions about Hi-Phi Nation: My posts about the show at Leiter Reports The American Philosophical Association Blog interview Vassar’s Interview Elucidations Podcast, extended discussion of the wishes of the dead My own philosophical work has been in epistemology and the philosophy of language, particularly on the nature of epistemic rationality, and in experimental semantics and pragmatics. I would be happy to have a discussion about those topics. In the past two years I’ve set technical research aside to produce what I hope will be an ongoing series of narrative story-driven philosophy akin to the best productions we have for economics and the social sciences, such as Freakonomics Radio and Invisibilia. It is my hope that having a high-production story-driven show about philosophy will open up the field to lots of new people, as well as let existing fans of philosophy appreciate the way it connects with journalism, history, law, and nonfiction writing.

He will look at this thread before he starts and begin with some questions from here while the initial questions in the new thread come in. Please join me in welcoming Professor Barry Lam to our community!

Hi Reddit, My name is Hui Wu, a Professor at the University of Alabama at Birmingham. My research focuses on microbial molecular mechanisms that contribute to oral infectious diseases, such as dental caries and periodontal disease. Specifically, I am interested in protein glycosylation pathways and using novel small molecules to inhibit bacterial biofilms. And I’m Jessica Scoffield, a Postdoctoral Fellow at the University of Alabama at Birmingham. My research examines competitive interactions between commensals (“friendly bacteria”) and pathogens that occur in polymicrobial infections. I am particularly interested in discovering unique antimicrobial mechanisms used by commensal bacteria to inhibit pathogenic bacteria. We recently published a study titled A commensal streptococcus hijacks a Pseudomonas aeruginosa exopolysaccharide to promote biofilm formation, in PLOS Pathogens. The purpose of the study was to characterize the two-species biofilm of Pseudomonas aeruginosa (a pathogen) and Streptococcus parasanguinis (a commensal), which are two bacteria that are present in the lungs of cystic fibrosis patients. Our study revealed that S. parasanguinis can utilize products made by P. aeruginosa to promote its own biofilm, while simultaneously restricting the incorporation of P. aeruginosa into the biofilm. Our findings suggest that commensals, such as S. parasanguinis, may be able to inhibit the persistence of P. aeruginosa. We will be answering your questions at 1pm ET – Ask Us Anything!

This past academic year the moderators of /r/philosophy organised an ongoing AMA series with 18 different philosophers working on a variety of different topics, from metaphysics to logic, bioethics to philosophy education. Our series has now officially come to an end, and we want to thank everyone for their support and participation. Special thanks go of course to our AMA philosophers, as well as Joy Mizan at Oxford University Press for helping reach out to a number of different people for us, as well as freeing up open-access materials from many different authors. Barry Lam AMA While we will not be running a summer AMA series, we do want to note that we will be running one final AMA before the fall, by philosopher Barry Lam, Associate Professor of Philosophy at Vassar College and creator of Hi-Phi Nation: A Show About Philosophy That Turns Stories Into Ideas. Professor Lam will be joining us on June 5 to discuss Hi-Phi Nation and the art of creating philosophy podcasts which appeal to both philosophers and non-philosophers. AMA Survey We’d like to take this time to open up a survey for you to comment on the AMA series; what you liked, what you didn’t, what’d you change, who you’d like to see, etc. Please take a couple minutes to take the AMA Series Survey so we can decide whether to run it again next year, and if so, how to do it. You can take the survey HERE. Thanks again to everyone who participated, and we hope that you found the AMAs as interesting as we did. We welcome all feedback in the hope that we can continue bringing great content to you in the future.

Hi Reddit, My name is Dr. David Robertson and I am Teaching & Research Fellow at the School of Psychological Sciences & Health, University of Strathclyde, Glasgow (UK). My research focuses on applied face recognition and the use of this biometric in policing and security contexts. I recently published a study (Robertson DJ, Kramer RSS, Burton AM (2017)) titled Fraudulent ID using face morphs: Experiments on human and automatic recognition in PLOS ONE. Across three experiments we assessed the extent to which human operators and a smartphone algorithm accepted face morphs as a genuine match to a target face. Face morphs do represent a route to identity fraud in humans and machine recognition systems, human detection of these images can be improved through awareness training. I will be answering your questions at 1pm ET. Ask me Anything! Don’t forget to follow me on Twitter @UOSPsychology York FaceVar Lab website here.

Hi, reddit! There are so many things we don’t know about the Universe. For example: What is most of the Universe made of? What is dark matter? Where does dark energy come from? Why does the universe have a speed limit? What (or who) is attacking earth with tiny, super-fast particles? And for that matter…what is matter? After generations of human research, brilliant scientific minds, and crazy technological advances we can confidently answer all of these questions the same way: we have no idea. In our new book WE HAVE NO IDEA: A Guide to the Unknown Universe we talk about why a vast portion of our universe (read: most of it) is still a mystery, and what a lot of smart people are doing to understand it. Ask us about physics, the universe – known and unknown, the Large Hadron Collider at CERN (Daniel works with it), illustration (Jorge’s the creator of PHD Comics), science in general, our deepest hopes and fears – in other words…ask us anything! We will be back at 4 pm ET (1 pm PT) to answer your questions.
