DESCRIPTION:Dr Dmitry Kireev\nABSTRACT\n\nThe modern neuro-electronic comp
 onents are rigid\, solid\, and stiff – a terrible match for soft\, squis
 hy\, and deformable tissue such as the human brain. The material mismatch 
 results in the conceptual incompatibility of modern electronics with biolo
 gical tissue. Nanoscale materials\, such as graphene and other 2D material
 s\, on the other hand\, are unique constructs: in addition to their appare
 nt unobtrusive atomic thickness\, they are flexible\, transparent\, and bi
 ocompatible\, matching perfectly with biological tissue.\nIn this talk\, I
  will introduce state-of-the-art implantable bioelectronic technologies an
 d expose their limitations. After uncovering the limits of modern technolo
 gies\, I will introduce to the audience how can we empower the next-genera
 tion neuroelectronic devices using 2D materials (graphene\, MoS2\, PtSe2\,
  PtTe2\, hBN\, and other emerging ones). Specifically:\n\n	I will show how
  graphene-based microelectrode arrays and field-effect transistors can be 
 used to efficiently communicate with neuronal cells\;\n	I will introduce a
 tomically thin electronic tattoos made of graphene that was used to non-in
 vasively monitor human electrophysiology in wearable conditions as the way
  toward building implantable systems\;\n	I will show our novel biocompatib
 le artificial synaptic transistors that can mimic biological synapse behav
 ior and provide the route toward tissue-like neuroelectronic implants\;\n\
 nLastly\, I will present my future plans to develop a unique toolbox of un
 conventional atomically thin neuroelectronic devices\, such as (1) PtSe2-b
 ased transistors (as signal pre-amplifiers) and PtTe2-based microelectrode
 s and piezoelectric energy harvesters as advanced transparent high-density
  cortical implants\, and (2) soft biocompatible artificial synaptic transi
 stor arrays capable of mimicking electrochemical neuronal behavior. Finall
 y\, I will introduce the concept of intradermal tissue-like electronics (3
 )\, which will essentially enable direct integration of the nanoscale elec
 tronic components with the tissue\, leading to the creation of life-long t
 issue implants and smart cyborg organs.\n\nBIO\n\nDr. Dmitry Kireev is cur
 rently a Research Associate at the University of Texas at Austin\, working
  on merging the fields of Neuroengineering\, 2D materials\, Bioelectronics
 \, Neuromorphic Computing\, and Nanoelectronics\, contributing to the deve
 lopment of bioelectronic devices with long-standing implications in Health
 care and Medicine.  He finished his PhD work in 2017 at the Institute of 
 Bioelectronics (ICS-8/IBI-3) of Forschungszentrum Julich and RWTH Aachen U
 niversity\, Germany\, working on graphene-based devices for neuronal and c
 ardiac in vitro bioelectronics. He is a recipient of a prestigious EMM-NAN
 O scholarship and performed his MSc studies in KULeuven (2012) and Chalmer
 s University of Technology (2013) with majors in nanoelectronics.\nDr. Kir
 eev has published 35+ primary research articles in broad scientific outlet
 s\, including high-impact journals (i.e.\, Nature\, Nature Nanotechnology\
 , Science Advances\, ACS Nano\, Advanced Materials\, Nano Letters)\, and f
 ield-specific topical journals (i.e.\, Advanced Healthcare Materials\, IEE
 E tNANO\, Carbon). Besides\, he published three book chapters and three re
 view articles\, contributing to the general development of the fields of b
 ioelectronics and 2D materials.\n
