Title: Exploring Many-Body Physics with Single Quantum Entities
for Quantum Information Science
Abstract: Future scalable and reliable universal quantum computers can be more superior than classical computers for solving certain problems. To fully harness the power of quantum mechanics, the quantum computing platform must be a many-body system with interacting or coupled quantum entities (qubits). For example, entangling multiple qubits requires coupling and coherence. The behavior of an assemble of interacting particles cannot be understood by a simple extrapolation of the microscopic lawas of single particles. Instead, entirely new properties can appear at each level of complexity, as pointed out by P.W. Anderson in 1972. Experimentally understanding new principles and laws in many-body systems is essential for both fundamental many-body physics and ultimately providing practical solutions for future scalable and reliable quantum computers.
In this talk, I will present our work in exploring many-body systems that consist of single quantum entities including single atoms and solid-state-based atom-like entities. Recent advances in the preparation of these exotic singe quantum entities and in coherent spectroscopy provide unprecedented opportutnties. We can deterministically prepare a few- or many-body quantum system of single quantum entities using a bottom-up approach and use ultrafast coherent spectroscopy to study many-body properties in these systems. For example, our results revealed long-range dipole-dipole interaction between atoms with separation up to tens of micrometers. We have also observed multi-atom Dicke states with a scalable and deterministic number of atoms from two to eight atoms, providing the prerequisite for generating entangled states of up to eight atoms. The study of these systems contributes to fundamental understanding of many-body physics as well as potential applications in quantum information science.

Title: Educating Beyond the Classroom: 36 Years in Rivers, Caves, Mountains, and Oceans
Abstract: Unionid mussels are the most imperiled taxa in the United States and are vastly understudied. This study aims to better understand unionid assemblage condition and distribution in large navigable rivers. The entire Robert C. Byrd (RCB) pool of the Ohio River is the study area. I selected sites from the 2019 and 2013 ORSANCO RCB pool assessments that utilize random site selection across the pool. I used SCUBA to survey and collect data on unionid diversity, reproduction, and habitat. Surprisingly, diversity in the Upper Section of Greenup Pool dwarfed all others. Patterns of species redundancy are determined utilizing NMS. RCB and Greenup Pool patterns are statically similar. Unique, this scope is a larger, pool-wide scale and is more representative of the current unionid assemblage. Data collected could serve as a baseline to site 鈥� specific surveys and have management implications for unionid assemblages in pools of large, navigable rivers.
Bio: I am a field biologist and an educator. My two 鈥渉appy places鈥� are on the bottom of the Ohio River in 20 feet of water, pushing me downstream in the dark, surveying for Unionid mussels and standing in some swamp, creek, wetland, mountain, tropical forest, or dock about to take students down on the reef for them to think, touch (carefully if required for study for stony coral), see, taste, hear, and do, science.
Interacting with my older colleagues, I hear; 鈥淪tudents are not what they use to be.鈥� 鈥淭hey are unprepared...鈥� 鈥溾�� are not focused.鈥� 鈥溾�� want hand fed information.鈥� 鈥淵es! Students today, aren鈥檛 what I was when I started!鈥� I believe that to be the most common quote of teachers across time. In part because we teachers are getting older and its hard not to get set in your ways. After all our 鈥渨ays鈥� are comfortable and less stressful on us. And we have found them to be effective in our past at teaching students. We can all name successful students who have flourished after learning from us.
But is it enough? I distinctly recall hearing my educational mentors saying, 鈥淚 work with the best 10% of my undergraduates as graduate students.鈥� This idea/attitude worked for them. In the past (?) for many/most students in the sciences, grad school was their first experiences doing science. How much less complex is it to provide a class, with a set of clean, concise data in Microsoft Excel as a starting point for a lab? Since post-WW2鈥檚 GI Bill universities have been flooded with students. Professors needed to prioritize their time by focusing in the hardest working, most motivated, most prepared students. This pattern resulted in large numbers of 鈥渘etworked鈥� former in fields that can help connect future students into that area. In fisheries/ichthyology how many of us can trace our academic history to 鈥淴鈥檚 lab鈥�? Two of my academic mentors were Dr Don Tarter and Dr Bill Pearson. Through their careers, I could go to any aquatic or fish meeting and make immediate connections to co-workers, former students, or folks at agencies who had worked with them. Telling stories over a beer is still a grand time for most of us at meetings.
Today things have changed. Our students鈥� educational experiences have changed, dramatically. I hope our educational goals have changed. Some folks didn鈥檛 benefit from the old boy network. In aquatics, fishes, and mussels our meetings are getting much better, but they are still too old, too white, too male, too straight, too neurotypical, too economically privileged, too different from the face of America. Too different from the future of America. My educational goals have changed, I want my students, as many as possible, to have a chance to be more than they expect they can be! To do more than they think they can. To have the education and experiences to prepare them for the careers they want. And to open many more to the ideas of a career way different from what they know now!

Title: High-throughput quantitative top-down MS
Abstract: Protein post-translational modifications (PTMs) have emerged in the post-genomic era as critical features in regulating and diversifying protein biological activity. In addition, various PTMs on the same protein tend to physically interact with each other, PTM crosstalk, that drives many signaling pathways. Thus, analysis of intact proteoforms is necessary for in-depth knowledge of the significance of various PTMs and related crosstalk. The overall purpose of my research program is to establish a high-throughput quantitative top-down proteomics platforms that combine top-down mass spectrometry (TD-MS) with novel sample handling and separation technologies. We have developed methods for high-resolution reversed-phase liquid chromatography (RPLC)-based separations (high pH and/or low pH) for analysis of complex protein mixtures such as cell lysates and serum samples. We also established and optimized a quantitative top-down proteomics workflow using intact protein-level tandem mass tag (TMT) labeling. Moreover, we have developed a novel analytical tool, 鈥渟pray-capillary鈥�, for quantitative ultra-low volume sampling (e.g., pL volume and sub-ng sample amount). The spray-capillary is capable of single-cell metabolomics or proteomics via the direct coupling of CE separation and MS detection requiring no additional devices. Overall, we envision these techniques as novel analytical tools to apply to the rapidly expanding field of real-life proteomics. To this end, we have applied quantitative top-down proteomics to the analysis of serum autoantibodies in patients with systemic lupus erythematosus (SLE). This research holds the potential to provide new insights regarding the autoantibody affinity maturation process and may lead to novel biomarkers for the diagnosis and treatment of SLE.

Title: Boosting Speed of Everything from AI to Wireless Communication via Waveform Processing Circuits and Chip
Abstract: The demand for high speed, reliable, and high data rate transmission in 5G/6G, radar, sensing, artificial intelligence, quantum computing, autonomous driving, smart health, smart living, virtual reality, and internet of thing (IoT) are continuously increasing, and emerging upscaled spectrum and efficient spectrum utilization are key methodologies to support those urgent needs of data transmission in different applications. These new spectrum and high speed with wide instantaneous bands bring unprecedented challenges for conventional electronic hardware systems. For example, high end multiple analog or digital filters are required in spectrum sensing hardware block, spurious frequency cancellation and low local oscillator frequency feedthrough are designed for frequency conversion block, high sampling rate, wideband, high-resolution analog to digital converters (ADC) are desired for signal conversion, and high-speed baseband processor are applied to execute complex signal processing, which fundamentally limits the operating speed and consume high energy and power. In this talk, I will discuss our recent research activities in reconfigurable real time radio frequency analog processors performing mathematical operation directly at analog waveform domain to mitigate the computation load in digital domain and signal processing and relax system stringent constraints.

Title: Selective Mitochondrial Autophagy in Health, Aging, and Disease
Abstract: The ubiquitin (Ub) kinase PINK1 and the E3 Ub ligase PRKN together mediate a cytoprotective mitochondrial quality control that selectively eliminates damaged mitochondria via the autophagy-lysosome system (mitophagy). Loss of function mutations in either gene are the most common cause of early-onset Parkinson鈥檚 disease (PD) and it is thought that failure to identify and clear damaged mitochondria eventually results in neuronal death. Beyond PD, mitophagy impairments seem to contribute more broadly to risk, onset, and progression of many age-related disorders of the brain and of other tissue with high metabolic demand. PINK1 surveys organelle health through its continuous import into mitochondria where it is cleaved and degraded. However, upon mitochondrial damage, PINK1 rapidly accumulates on the outer mitochondrial membrane. This leads to phosphorylation of the small modifier protein Ub and the Ub-like domain of the E3 Ub ligase PRKN at a conserved Ser65 residue. The phosphorylation of Ub (pS65-Ub) serves as an allosteric activator of and receptor for PRKN on damaged mitochondria. Once translocated to mitochondria, PINK1 and PRKN jointly act as an enzymatic pair amplifying the formation of phosphorylated Ub chains that serve as the 鈥榤itophagy tag鈥�. As such pS65-Ub is a specific and quantitative marker of mitochondrial damage and further facilitates transport to and elimination of damaged mitochondria in lysosomes. We have recently developed means to assess and follow pS65-Ub in cells and tissues as well as in blood samples from animal models and patients. In addition, we started exploiting pS65-Ub as a quantitative trait for genetic and cell-based screening to identify novel mitophagy modifiers and candidate risk factors. Additional efforts are underway to determine the suitability of pS65-Ub as a potential disease or pharmacodynamics marker and to capitalize on structure-function relationships for drug development to activate the protective enzyme pair PINK1-PRKN.
Bio: Dr. Wolfdieter Springer is a Consultant and Associate Professor in the Department of Neuroscience at Mayo Clinic in Jacksonville, Florida. His main research focus is on the molecular and cellular mechanisms underlying aging and age-related neurodegenerative disorders. He received his MSc from the University of Regensburg and his PhD from the Ludwig-Maximilian-University in Munich, Germany. His postdoctoral training at the Hertie-Institute for Clinical Brain Research in Tuebingen, Germany, led to the seminal discovery of the PINK1-PRKN pathway that orchestrates the selective degradation of damaged mitochondria via the autophagy-lysosome system (mitophagy). Dr. Springer鈥檚 laboratory at Mayo Clinic continues to study this ubiquitin kinase-ligase pair on a structural, cellular, and organismal level with a focus on relevance of mitochondrial autophagy in health, aging, and disease. Current efforts aim at dissecting the genetic architecture and regulation of mitophagy and the development of biomarkers and future therapeutics for diseases where mitochondrial, autophagic, or lysosomal dysfunctions emerge as a common theme. Dr. Springer鈥檚 research is funded by multiple sources including the National Institutes of Health, the Department of Defense, the Michael J. Fox Foundation for Parkinson鈥檚 Research, and others.
