SUMMARY:Fishes\, worms\, and human aging
DESCRIPTION:Ayça Arslan Ergül\nMSN Graduate Program and UNAM \n\nIn this talk I will not focus on one research\, but instead I will try to give glimpses of all the topics that we work on or ideas that we nourish. In this way you may also join or contribute to one of the projects\, if you get interested. Arslan-Ergul lab has been founded in January 2021 in UNAM\, so we are celebrating our first year. Our research interest can be summarized in one word as aging\, in several words as brain aging\, neurodegeneration\, adaptation\, genetics\, and behavior. \n \n  \nAbout Speaker\nAyça Arslan Ergül was graduated from Boğaziçi University\, department of Molecular Biology and Genetics. She did her PhD in Bilkent University Molecular Biology and Genetics department\, on liver cancer and cellular senescence. In Scotland\, Glasgow\, she worked on cell-targeted therapies. For five years\, she worked in Bilkent University UNAM\, on brain aging and new cell formations and taught for the Neuroscience program. She was nominated as Changemaker by Sabancı Foundation for running the Friends\, lets do science project as a volunteer. On her YouTube channel she is teaching molecular biology. She is living with her husband Özgür Ergül and three cats. \n\nJoin Zoom Meeting\nhttps://zoom.us/j/95581724217 \n\n

SUMMARY:What can we learn from computational cell models?
DESCRIPTION:Aykut Erbaş\nMSN Graduate Program and UNAM \n\nThere are over 40 million cells in our body. Despite carrying an identical genome\, these cells are specialized into 200 different types to undertake particular biological tasks in various tissues. The main factor determining a cell’s biological identity is the type and amount of cell-specific proteins. In turn\, these cell-specific proteins somewhat determine how\, when\, where\, and which part of genetic information encoded in our DNA will be read to sustain the dynamic complexity of cellular activity. One of the questions that we ask in our research group: can we use minimal computational models to reveal certain parts of this complexity? By considering the kinetics and organizational properties of DNA-binding proteins\, in this talk\, I will present a couple of examples to convince you that computer simulations can be used\, along with biomolecular experiments\, to elucidate the dynamic and organizational properties of the genome. Together we will see that well-designed molecular models can replicate experimental findings and encourage us to reconsider even re-write certain parts of our text-books. \n \n  \n  \nAbout Speaker\nDr. Aykut Erbaş completed his Ph.D. in Physics at Technical University Munich (TUM)\, Germany\, in 2011. His Ph.D. thesis contributed to the understanding of biomolecular mobility\, specifically\, of disordered protein structures. Later he moved to the Chemistry Department at the University of North Carolina – Chapel Hill to research polymer dynamics. Between 2014 and 2018\, Dr. Erbas was a research fellow at the Material Science & Engineering Department at Northwestern University under various centers dedicated to designing bio-inspired energy systems. He also researched the interaction kinetics of biomolecular systems and molecular self-assembly in collaboration with Northwestern Biomolecular Sciences and Chemistry Departments. Dr. Erbas has been actively working on various soft-matter systems in close collaboration with experimental and engineering groups. He is currently interested in the kinetics aspects of protein-DNA interactions and 3d genome organization in his lab. Dr. Erbas has been an assistant professor at UNAM since September 2018 \n\nJoin Zoom Meeting\nhttps://zoom.us/j/95581724217 \n\n

SUMMARY:Towards reconfigurable digital complex photonic systems
DESCRIPTION:Hasan Yılmaz\nMSN Graduate Program and UNAM \n\nOptical waves scattered or emitted by materials carry information in temporal (spectral) or spatial domains. Perhaps\, the most prominent example of optical information is an optical image that is created by an optical microscope. With the emergence of information technology\, optical information can be digitized and computationally processed. Computational optical imaging systems typically map spatial and spectral information of light waves to the spatial properties of materials. However\, most optical materials are complex (three-dimensional and opaque): we cannot see inside or behind them. This is because opaque materials’ refractive index is inhomogeneously distributed in space. Incident light waves scatter into random directions upon propagation through opaque materials such as clouds\, mil kor biological tissue\, which scrambles the spatial information. Such a random light scattering process complicates the mapping between scattered light waves and three-dimensional structures. \nIn this talk\, first I will introduce the transmission matrix concept which maps the incident light waves to the scattered light waves through complex optical materials. The main ingredient of this talk will be the ‘transmission-matrix-based operator’ approach. I will show that the transmission matrix not only enables us to transport optical information through a complex material (e.g. a layer of white paint or multimode fiber)\, but it also enables us to modify the relationship between certain incident waves\, scattered waves\, and the configuration of the system. Our ‘transmission-matrix-based operator’ approach provides a general framework for designing and creating a desired input-output relationship of classical and quantum light waves for various applications in imaging\, metrology\, and communication through complex materials. \nFinally\, I will introduce the inverse scattering problem in complex photonic systems such as multiple-scattering materials. Benefiting from the ‘transmission-matrix-based operator’ approach\, I will briefly propose reconfigurable digital complex photonic systems. Such systems will not only be ideal hardware platforms to physically simulate inverse scattering problems but also lead to reconfigurable multimode photonic devices such as dynamic mode converters\, mode demultiplexers\, etc. \n \n  \n  \nAbout Speaker\nHasan Yılmaz is currently an assistant professor at Bilkent University\, the Institute of Materials Science and Nanotechnology. His research interests cover experimental and computational optics and photonics\, light scattering\, optical imaging and spectroscopy\, computational imaging\, wavefront shaping\, spatiotemporal control of light\, complex photonic materials\, mesoscopic physics of light\, statistical optics\, laser physics and random matrix theory. \nPreviously\, he worked as a postdoctoral associate and an associate research scientist at Prof. Hui Cao’s lab\, Yale University\, the Department of Applied Physics. He has received a Ph.D. degree from the University of Twente in the Netherlands for his thesis entitled “Advanced Optical Imaging with Scattering Lenses\,” with Prof. Allard Mosk in 2015. Before this\, he has received a M.Sc. degree in Materials Science and Engineering at Koç University\, where he worked with Prof. Ali Serpengüzel at the Microphotonics Research Laboratory. He has a B.Sc. degree in Physics Engineering from İstanbul Technical University. \n\nJoin Zoom Meeting\nhttps://zoom.us/j/95581724217 \n\n
