Cryptography, Security, and Law

Sunoo Park

Assistant Professor

NYU | Courant Computer Science

November 16, 2023 12Noon-1pm – Room N923

My research focuses on the security, privacy, and transparency of technologies in societal and legal context. My talk will focus on three of my recent works in this space, relating to (1) preventing exploitation of stolen email data, (2) enhancing accountability in electronic surveillance, and (3) legal risks faced by security researchers.


Bio: Sunoo Park is an Assistant Professor of Computer Science at NYU’s Courant Institute of Mathematical Sciences and Affiliated Interdisciplinary Faculty at the NYU School of Law. Her research is in technology law and policy, cryptography, and computer security.

Understanding Cloud Computing

Daniel Alvarez

Enterprise Solutions Architect

September 28, 2023             12Noon-1pm
Room N923


Many feel they understand the concept of cloud computing, but few fully grasp the scope of what’s possible and why it matters for their roles. During this one hour lecture, we’ll go over the comprehensive definition of cloud computing, the role of AWS, the business model and value proposition for companies, core concepts, and how you can get started learning about the cloud and AWS. This lecture will be given at a 100-level depth and is suited for students, faculty, and City Tech/CUNY administrators alike.

DDoS: a 20-year journey from compromised workstations to IoT attacks

Sven Dietrich

Math & Computer Science Dept.

John Jay College of Criminal Justice

April 11, 12pm-1pm

Room N923


In this 20-year retrospective, we discuss some of the challenges of dealing with distributed denial-of-service (DDoS) attacks from its origins in 1999 to the recent attacks in the late 2010s.  We describe first architectures of DDoS agents, the challenges of DDoS agent/bot forensics, the variety of topologies and command-and-control mechanisms for botnets over the years, the different victim populations from scientific workstations to IoT devices, future and current Internet design considerations, as well as attack and defense mechanisms at the host and network levels.




Building noise robust machine listeners with data and inspiration from humans

Michael Mandel

Associate Professor

Brooklyn College, Graduate Center

November 8, 12pm-1pm

Room N919


Matching human performance is one of the most difficult problems for a variety of speech communication technologies, including automatic speech recognition, voice processing in hearing aids, and mobile telephony.  One theory of human noise robustness is that listeners pick out reliable “glimpses” of a target sound and utilize contextual clues to fill in missing information using top-down knowledge.  This talk presents work that brings both of these processes to machines.



Driving Enterprise Transformation with Virtual & Augmented Reality

October 11, 12pm-1pm
Room N919


Enterprises are embracing Virtual and Augmented Reality, using VR and AR to transform the way businesses work, train their staff, collaborate, communicate and interact with clients. We will examine the current trend of VR and AR usage from different industries such as Aviation, Automobile and Retail with a specific emphasis on use cases for the Architectural, Engineering and Construction industry.



Eager Execution in TensorFlow

Alexandre Passos

Software Engineer Google

April 12, 12pm-1pm Room N923





In this talk we’ll go over TensorFlow, an open- source cross-platform machine learning library developed by Google, and explore its new feature: eager execution. We’ll go over how to use it to write dynamic models, to debug and profile models, and to learn deep learning.
