HopHacks is the biannual hackathon hosted at Johns Hopkins University in Baltimore, Maryland. For 36 hours students work in teams of up to four people, to bring a software or hardware idea to life. Last spring, we gathered more than 360 of the most creative and talented students from JHU, MIT, UMD, CMU, Rutgers, NYU, and many more. This September 14 through 16, we expect to host even more students from institutions across the country and welcome you to join the HopHacks community.Learn More
Join us for Johns Hopkins Engineering Alumni Career Night! A small alumni panel sharing their real-world experiences, followed by an open networking reception for panelists, all alumni attendees, and engineering students.
The Research Internships in Science and Engineering (RISE@APL) program allows highly qualified undergraduate and graduate students from the Whiting School of Engineering and the Krieger School of Arts and Sciences the opportunity to conduct research at the Johns Hopkins Applied Physics Laboratory.
At this poster and information session, RISE@APL Scholars will present their research findings, while representatives from APL and Johns Hopkins Engineering will be available to answer students’ questions about the application and selection process.
The Whiting School of Engineering and the Krieger School of Arts and Sciences invite all students to attend our annual Mock Interview Night. Students will be paired with alumni to get helpful interviewing tips during one-on-one interviews.

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.
David M. Van Wie, PhD, will present “Hypersonics: Back to the Future.”
Hypersonics is defined as flight at speeds above Mach 5—five times the local speed of sound. Currently, there is a resurgence of interest in hypersonic systems for applications such as weapons, rapid commercial transportation, and space launch. To realize these new applications, technology advancements are needed in the areas of novel thermal protection systems, high-temperature materials, advanced guidance, navigation and control, and propulsion. For more than 60 years, researchers at the Johns Hopkins University Applied Physics Laboratory have been investigating hypersonic technologies and applications, including Frederick S. Billig’s pioneering development of scramjet engine technology. Dr. Van Wie will offer a brief history of hypersonics highlighting Dr. Billig’s contributions and will discuss ongoing technology development challenges in this area.
