Abstract

Efficient drug delivery remains an important challenge in medicine.  Continuous release of therapeutic agents over extended time periods and in accordance to a pre-determined temporal profile; local delivery at a constant rate to overcome systemic toxicity; improved ease of administration, and increasing patient compliance are some of the unmet needs of the present drug delivery technology. This talk will discuss in vivo drug delivery strategies that capitalize on the strengths of micro and nanofabrication. By taking advantage of our ability to control topography and chemistry at submicron size scales, we have developed organic and inorganic interfaces which modulate cell function while at the same time allow for controlled drug release kinetics. Due to our ability to create monodisperse features as small as several nanometers in a variety of non-planar biocompatible materials, these interfaces offer advantages in their reproducibility, stability, and their ability to intimately contact cell and tissue surfaces.  Such nanoengineered interfaces may be optimized for biomolecular selectivity and surface bioactivity, leading to unique interfacial properties not achieved through existing drug delivery approaches. Such micro/nanofabrication approaches can enhance current drug delivery platforms while becoming an enabling technology leading to new basic discoveries in the biological sciences.

PRESENTATION: Airline Operations: A passenger-centric perspective
DATE: Thursday-January 29, 2009
TIME: 11:00 AM
LOCATION: 1043 ERF, 842 W. Taylor Street, Chicago

ABSTRACT:

Even with numerous efforts to optimize operations, flight delays have long
plagued the airline industry.  In this talk, we provide an analysis of
airline delays, and discuss the impact that airports, airline scheduling
practices, passenger load levels and weather have in influencing the
amount and frequency of delays experienced by passengers.  Further, we
show the correlation (or lack thereof) between passenger delays and
aircraft delays, and evaluate the effectiveness of US Department of
Transportation delay metrics to inform and protect the traveling public.
We conclude with suggestions of how operations research can be applied to
help address airline delay issues. 


Dr. Karen Vogtmann

Professor of Mathematics
Cornell University
Trustee, American Mathematical Society

RECEPTION:
DATE: Monday - October 13, 2008
TIME: 3:00 PM
LOCATION: SEO 300

PRESENTATION:
DATE: Monday- October 13, 2008
TIME: 4:00 PM
LOCATION: Lecture Center D4

BIOSKETCH:

Inspired to pursue mathematics by an NSF summer program for high school students at the University of California, Berkeley, Karen Vogtmann received both her undergraduate and graduate degrees from Berkeley. After holding positions at the University of Michigan, Brandeis University, and Columbia University, she settled at Cornell University where she has been for the last twenty years. A distinguished mathematician, she has authored numerous articles, mentored nine PhD students, and given several invited talks including a lecutre at the International Congress of Mathematicians. Vogtmann has served as Vice President of the American Mathematical Society and on scientific advisory boards of the American Institute of Mathematics, the Mathematical Sciences Research Institute, the National Academy of Sciences Delegation to the International Mathematical Union General Assembly, and the Vietnam Education Foundation Panel for mathematics.

Vogtmann’s research views groups as symmetries of geometric objects. By understanding the geometry and topology of suitably chosen objects, she deduces algebraic information about the groups acting on them. Her work investigates orthogonal and symplectic groups, SL(2) of rings of  imaginary quadratic integers, groups of automorphisms of free groups, and mapping class groups of surfaces. Vogtmann’s recent focus has been on the group of outer automorphisms of a free group where the appropriate geometric object is called Outer Space. This space turns out to have surprising connections with other areas of mathematics, for example with certain infinite-dimensional Lie algebras and even with the study of phylogenetic trees in biology.

TITLE:

Symmetries, Ping-pong, and Outer Space

ABSTRACT:

The symmetries of any geometric object form a system which obeys a small set of natural “rules."   Mathematicians have observed that systems obeying the same set of rules occur throughout  mathematics, though with wildly different descriptions.  Since such systems, called groups, lie at the heart of many calculations in mathematics and the sciences, we are very interested in trying to understand them better.  The branch of mathematics in which I work, called geometric group theory, studies abstractly defined groups by trying to find  concrete geometric objects whose symmetry groups are basically the same as the group under investigation.  A close look at such an  object often reveals characteristics of the group which were not obvious from the original description. A nice aspect of geometric group theory is that the search for such objects and attempts to visualize them often lead to very beautiful  mathematical imagery.

One of the simplest of all types of groups are the so-called free groups; here the word free can be interpreted as saying that the group is free of any complicated internal structure. It is often very useful to be able to recognize when a group which looks like it might be very complicated is in fact secretly just a free group.  One very appealing way to solve this problem is to find an appropriate geometric object, which we then use as a table on which to play  mathematical ``ping-pong";  the reason for this name becomes clear after seeing an example. Much of my work involves trying to understand symmetries of free groups.    I will describe an appropriate ping-pong table, known as Outer space,  which can sometimes be used to settle this question.

Departmental Lecture "Dielectric Films with Metal Nanoparticles for High-k and Non- Volatile Memory Applications"

Monday November 5, 2007 at 10:00 AM in ERF 1043 & 1047

ABSTRACT Departmental Lecture

High-κ dielectrics have become a focal point of the complimentary metal oxide semiconductor (CMOS) front end. Controlling threshold voltages in upcoming nodes will require dielectrics which have both suitable properties on contact with silicon and a high permittivity. Our research has focused on using silver, platinum and gold nanoparticles to enhance the dielectric constant of amorphous HfO2 and Al2O3. Metal nanocrystals of diameter down to 1nm are incorporated in high-K dielectrics for achieving non-volatile memories. Nanocrystal based non-volatile memories are discrete charge storage devices and are strong candidates for replacement of conventional FLASH memories. 

General Lecture

"Nano-Engineered Material and Applications in Life Sciences"

Tuesday November 6, 2007 at  2:00 PM in SEO 1000

ABSTRACT General Lecture

We are currently developing a micro system based on nano-engineered thermite materials capable of generating a large and controlled amount of energy via super-sonic pressure pulse, known as a shock wave. This shock wave can deliver different materials into single cells or tissue with extremely high precision without damaging cells/tissues. We are also preparing biocompatible nanoparticles that will permit the clustering of high doses of medical compounds, fluorescent dyes, plasmids, etc into a small compartment. Together these elements will comprise a high efficiency delivery system capable of transfecting cells or tissue with extremely high accuracy and with minimal side effects. The tunable, hand-held system will bring fundamental changes to the study and understanding of biological processes in health and disease, as well as enable novel diagnostics and interventions for treating disease. Thus, the technological advances from this study could result in a new era in the treatment and/or diagnosis of cancer, Parkinson’s disease, Alzheimer’s, spinal cord injury, thrombosis, cardiovascular diseases and host of other conditions.

UIC WISEST VISITING SCHOLARS PROGRAM hosted Dr. Paula T. Hammond, 2:00 PM, Thursday, September 27, 2007, Lecture Center A1.

The presentation titled "Building Materials One Nano-Layer at a Time: An Introduction to Chemical Engineering and Nanotechnology" is open to the public with undergraduate students, graduate students, and faculty from all disciplines encouraged to attend. Dr. Hammond is the Bayer Chair Professor of Chemical Engineering at Massachusetts Institute of Technology.

ABSTRACT

By electrostatically depositing alternating layers of oppositely charged molecular layers, Professor Hammond's group has developed the first class of thin films that can release drugs, and even genes, in an exact sequence and at a predetermined rate, and afterwards break down in the body. Applied to orthopedic implants, one layer of coating would locally inhibit infection through release antibiotics and anti-inflammatory drugs right after the surgery, followed by the release a protein-like growth factors from subsequent layers to stimulate the growth of bone in order to secure the implant in place. For tissue engineering, these coatings could be used for evolvable materials scaffolds onto which cells can grow and have growth factors introduced over time, or have specific genes introduced over time that program them their development. Exciting research in functional thin films (at the disciplinary interfaces between electroresponsive systems, nanoscience and biology) shows promise toward transparent coatings for replacement lenses used in cataract surgery and also electrochemical means of drug delivery.
