Inaugural Professorial Lecture: Joel Bader @ Mason Hall Auditorium

Joel Bader will deliver a lecture as part of the Don P. Giddens Inaugural Professorial Lecture Series. Bader is a professor in the Department of Biomedical Engineering.

Stopping Cancer Metastasis

Cancer’s lethality comes not from the growth of the original tumor, but from the spread of the disease to distant sites in the body. Professor Bader will describe ongoing work to dissect the gene and protein networks driving cancer metastasis, suggesting targets for therapeutic intervention.


The Don P. Giddens Inaugural Professorial Lecture Series began in 1993 as a way to honor newly promoted full professors. Professor Giddens, originator of the series, served as the fifth dean of Engineering at Johns Hopkins.

Noah Cowan will deliver a lecture as part of the Don P. Giddens Inaugural Professorial Lecture Series. Cowan is a professor in the Department of Mechanical Engineering.

Neuroscience in The Matrix

Understanding how the nervous system encodes and processes sensory information, transforms it into meaningful intermediate representations in the brain, and computes motor output involves decoding a complex closed-loop control system. Professor Cowan will present research devoted to developing and applying ideas in engineering to decode closed-loop neuromechanical control in animals, including humans.

Re-Envisioning Wastewater Treatment for the 21st Century

Abstract: The philosophy of municipal wastewater treatment has changed only slowly in the past 100 years. From approximately 1920 to 1970, a wastewater discharge was considered acceptable if the dissolved oxygen level in the receiving stream did not dip below 5 mg/L downstream of the discharge. Protecting aquatic life, particularly fish, from immediate death due to low oxygen levels was the primary motivation and the goal. The passage of the Clean Water Act in 1970 reflected a broader view to include concerns about eutrophication by nutrients and ecological and human health concerns with the naming of “priority pollutants.” Nevertheless, the central concept was that discharge concentrations would be acceptable if they took advantage of the assimilative capacity of receiving waters; that is, if they limited the harm to acceptable values. Now we are embarking on a new philosophy, captured by the phrase “One Water” by the Water Environment Federation, in which we think of wastewater not as a problem for disposal but as a resource.

Why is this shift in philosophy happening? At least two major changes have occurred since the old philosophies were developed. First, a dramatically increased population has led to a substantial increase in “indirect potable reuse” of wastewater, whereby the effluent discharge from one city is a part of the drinking water source for a downstream city. In many areas of the arid Southwest, that “part” can often be nearly 100%. An extension of this trend, due to water shortages, is the drive toward direct potable reuse of wastewater. Second, not only do the chemical and pharmaceutical industries now produce tens of thousands of synthetic chemicals that were not dreamed of when the “priority pollutant” list associated with the Clean Water Act was developed, we now understand that some of these products are endocrine disruptors and others lead to microbial antibiotic resistance.

In this talk, I will try to make the case that wastewater treatment needs to be changed, perhaps radically, to reflect the new philosophy and to meet the needs of the 21st century. The thrust of the presentation will be to explore some possibilities for these radical changes and try to back them up with preliminary engineering calculations.

Inaugural Professorial Lecture: Rachel Karchin
Apr 18 @ 4:00 pm – 5:00 pm
Inaugural Professorial Lecture: Rachel Karchin @ Mason Hall Auditorium

Rachel Karchin will deliver a lecture titled “Computational modeling of cancer precursor lesion evolution” as part of the Don P. Giddens Inaugural Professorial Lecture Series. Karchin is a professor in the Department of Biomedical Engineering.

Genome sequencing studies of tumor samples from large patient cohorts have provided convincing support for the somatic mutation theory of cancer, which posits that neoplasms result from mutational activation of oncogenes and mutational inactivation of tumor suppressor genes. Tumor cells originating from the same ancestral lineage form clonal populations, and the size and time-ordering of the clones can be modeled by hierarchical tree structures. In this lecture, Professor Karchin will discuss her research group’s reconstructions of precursor lesion evolution in high grade serous ovarian cancer and pancreatic adenocarcinoma.
