01 From Theory to Revolutionary Instrumentation: Nothing is More Practical than a Good Theory?
Fundamentals Interest Group
Presiding: Alexandre Shvartsburg; Alexander Makarov
We will focus on the connection between theoretical advances in ion dynamics and novel MS instrumentation, discussing the fundamental underpinnings and limitations of breakthrough MS platforms that revolutionized mass spectrometry since 2000.
Recent history of MS amply showcases the "Nothing is more practical than a good theory" dictum by
US psychologist Kurt Lewin. New (often seemingly esoteric) physical concepts and developments in ion motion simulations were translated into novel MS systems of unprecedented resolving power and sensitivity providing analytical capabilities previously deemed beyond reach.
We will seek to identify the key conditions that precipitated the transition from theory (often around for decades) to the technological breakthrough. A juxtaposition to the above quote is “The great tragedy of science - the slaying of a beautiful hypothesis by an ugly fact” (Thomas Huxley). Commonly that happens to the initial model, and progress to practical implementation requires refined understanding. We will explore this yin-and-yang dynamics in several areas, tentatively:
- Ultrahigh-resolution MS: from the Kingdon trap physics to Orbitrap MS
- Ultrahigh-resolution IMS: from the traveling-wave and synchrotron IMS concepts to Cyclic IMS
- High-resolution FAIMS: leveraging the non-Blanc effects in gas mixtures
- Electron Capture Dissociation: from a peculiar FTICR feature to mass-market technology
02 Ambient MS and Direct to MS: Strategies for Quantitation
Ambient Sampling & Ionization Interest Group
Presiding: G. Asher Newsome; Germán Gómez-Ríos
The ease and approachability of ambient ionization and direct to MS sources have made them popular methods for qualitative analysis since the mid-2000s, but the operational elements that allow speed and minimal-to-no sample preparation are often at odds with the requirements for quantitation. At ASMS 2019, workshop attendees responded to a poll by rating “quantitative capabilities” and “reproducibility” as the top challenges in ambient ionization. Having discussed reproducibility (and lack of reproducibility) with short, virtual talks at the 2020 Reboot, this year we will host a panel of experts with hands-on experience to discuss challenges and strategies for quantitation with various sampling and ionization methods and analytes. The panel Q&A will be preceded by several 3-minute lightning talks selected from 2021 posters to share hot topics in ambient sampling and ionization. The workshop aims to encourage audience participation and presentations from new investigators, postdocs, and graduate students with a balanced perspective from inside and outside academia. The workshop will also review the new status as an interest group and solicit topics for discussion in future years.
03 Interpreting Imaging MS Data at 'Omics Level: Integration with Other Omics Platforms
Imaging MS Interest Group
Presiding: Alison Scott; Jens Soltwisch
Room 201 ABC
Progress continues to be made in interpreting imaging mass spectrometry data at the omics level and validating imaging results with other omics techniques for comprehensive spatial omics. From these investigations, several new software tools and experimental strategies have emerged to more confidently interpret metabolomics and proteomics imaging MS data in biological and pathological contexts. In this workshop, we will discuss these tools, their strengths and how to address current limitations. Preliminary topics to be addressed include:
1) Current software solutions for omics level interpretation of imaging MS data
2) Pathway analysis integration with IMS
3) How to integrate imaging interpretation software with other omics software
4) Advanced analytical methods for validation of identities in imaging MS
The workshop will entail short presentations by students, postdoctoral fellows, investigators from industry, academia, and government laboratories. Each presentation will be followed by a 5-10 minute discussion within the interest group. A goal is to further disseminate information on challenges and solutions for integration of imaging MS with other omics platforms for confident biological interpretation.
04 Ion Mobility MS Data Analysis Tools: What's There and What Isn't
Ion Mobility MS Interest Group
Presiding: Ian Webb; Kelly Hines; Xueyun Zheng
Room 204 ABC
The rapid development and adoption of ion mobility-mass spectrometry (IM-MS) instrumentation and methods has led to the production of data from a huge variety of experiments. The multidimensional data that is generated by IM (e.g., LC/IM/MS/MS) is incredibly rich due to the high peak capacities of each dimension. However, the complexity of recent experiments and the resulting data have outpaced the existing capabilities for IM-MS data analysis and interpretation. The demand for these new tools is exacerbated by the unique data architectures used by each of the major IM-MS instrumentation vendors. Thus, the development of a suite of cross-platform data analysis, informatics and visualization tools for multidimensional IM-MS experiments is critical to the advancement of the field.
There have been many software tools developed by both the vendors and the users to analyze IM data. For instance, IM-MS tools that currently exist include software for IM-MS feature finding and deconvolution, targeted quantitative measurements, native MS structural analysis, and others. The workshop will provide the community with an overview of the ion mobility-mass spectrometry software tools that have been developed and their applications. This workshop will emphasize diverse topics focusing on the many types of experiments that are performed with IM-MS, including quantitative and qualitative studies ranging from metabolite and small molecule analysis to native IM-MS/structural proteomics. We intend to provide a venue for discussion of the various capabilities and applications of the available tools and give the community an opportunity to discuss their unique applications that may not have the necessary tools available.
05 The International Metaproteomics Initiative: Communicating and Advancing Metaproteomics Research
Presiding: Pratik Jagtap; Robert Hettich; Timothy Griffin
Room 102 AB
Mass spectrometry-based metaproteomics research has experienced rapid and recent growth due to its ability to help understand how microbiomes function. Leading metaproteomics researchers from multiple countries recently announced the launch of the Metaproteomics Initiative (www.metaproteomics.org). This global initiative aims to promote the dissemination of metaproteomics fundamentals, analytical and bioinformatic advancements, and applications via a collaborative community-based network focused on microbiome research. The Initiative will maintain a central information hub where newcomers and experts can interact to communicate, share ideas and data, and accelerate experimental and bioinformatic methodologies in this field.
The workshop will introduce the Initiative along with information on how interested researchers can join, participate and contribute to the growth. The workshop will also include an update on the Initiative's latest projects and publications. We will invite a panel of leading metaproteomics experts who will participate in a discussion that spans topics such as their motivation in joining this initiative; the current status of metaproteomics and potential challenges and opportunities in metaproteomics. The panel will also interact with the audience and address discussion points on how the initiative will help in gaining deeper insights into microbiome dynamics.
06 MS Libraries for Compound Identification
Presiding: Xiaoyu Yang
Room 103 ABC
Panelists: Oliver Fiehn, Stephen Stein, Tim Stratton
Mass spectral (MS) libraries are widely used in almost all areas of science seeking the identification of molecules. The objective of this workshop is to provide an up-to-date forum on the latest development of MS libraries and for participants to share their related experience, suggestions, problems and concerns. The workshop will focus on the practical use and application of the MS libraries and associated software tools for compound identification. A workshop presider will first give an overview of the MS library application in human health, food, and environmental analysis. Three experts (panelists from academia, industry and government) will then describe recent developments, their insights and opinions about MS libraries, applications, and useful software tools that they utilized in their studies and projects. After a short Q&A session, the discussions will be led by the panelists and topics will include: available MS libraries, their features and limitations for LC/MS/MS and GC/MS data analysis in metabolomics, (glyco)proteomics, lipidomics, forensics, and environmental studies; library searching methods, software tools and their pros and cons; integration of libraries in other software platforms (e.g. Skyline); combining library searching with peptide sequence database searching; applying artificial intelligence (AI) in spectral prediction for compound identification. At the end of the workshop, we hope participants will learn how MS libraries can efficiently help their data analysis and what software tools can make it easier.
07 Developing World Outreach
Developing World Outreach Interest Group
Presiding: Kym Faull; Hendrik Kersten; Giles Edwards
Room 104 AB
The idea is to bring together members of our society who wish to contribute to mass spectrometry related education and research in the Developing World. This goal is considered by some as an important step toward addressing issues mankind is facing, and will be facing in future. One central point is the transfer of discarded, but still running instruments to institutions in countries that could otherwise not afford them. However, there is a long way from goodwill to meaningful scientific data, paved with administrative, technical and educational hurdles. Sustainable development requires a committed network of experienced mass spectrometrists who can provide on-site installations, training, potential equipment for donation and contact persons who are prepared to share knowledge, time, and expertise. The News and Views section of the October 2019 JASMS issue broadly informed our society about the current efforts and needs, in particular about the work of RORO (Recycling Organization Research Opportunities), a registered charity organization operating in this field since 2006. To maintain the momentum and further develop this network we need to meet, discuss and organize things at this year´s workshop. The agenda includes a report on the current status and capabilities of RORO and a broad discussion centered on bringing mass spectrometry to the Developing World. The session will be jointly organized and chaired by Kym Faull, Hendrik Kersten, Giles Edwards and Abraham Badu.

These stories would include experiences with trying to navigate work-life balance amidst COVID pandemic amongst others. This will offer a unique viewpoint to audience in addition to providing a basis to ask more involved questions. Next, Q & A session will commence where participants can ask questions both in-live and through online portal leading to an active discussion.
10 LC-MS for Translational DMPK and Precision Medicine
DMPK Interest Group
Presiding: Brian Rago; Bhagwat Prasad
Room 110 AB
Translation of in vitro and preclinical drug metabolism and pharmacokinetic data (DMPK) to human is important for drug development. However, differences in the abundance of drug metabolizing enzymes and transporters (DMETs) between in vitro systems and preclinical and human tissues pose an important challenge in translating these data. The protein abundance characterization of DMETs by either LC-MS targeted or global proteomics and integration of these data into physiologically-based pharmacokinetic (PBPK) models provide a key solution to this problem.
Similarly, characterization of variability in drug disposition is important for clinical study design and precision drug treatment. Since variability in drug disposition cannot be completely described by genetics, characterization of phenotypic variability is critical.
This has fostered the development of plasma-derived exosomes as liquid biopsy and endogenous biomarkers for the prediction of drug metabolism and transport. Integration of metabolomics and proteomics data PBPK models also supports data translation for better prediction of drug disposition.
This workshop will provide an update on various non-invasive and in silico approaches for drug disposition prediction that will include application of transporter proteomics in PBPK modeling, utilizing exosomes for drug disposition prediction, and DMET proteomics in precision medicine.
