"Unraveling a web of mysteries"


Dynamical algebraic combinatorics studies actions on mathematical objects with strikingly nice counting formulas and algebraic significance.
Often, the study of such dynamics provides insight into the structure of the objects, revealing hidden symmetries and connections.
In this talk, I'll describe some recent work on mathematical objects called webs, in which we found a beautiful,
visual explanation of nice dynamical behavior which led us to a solution of a 30-year old problem.
(Joint work with Christian Gaetz, Oliver Pechenik, Stephan Pfannerer, and Joshua Swanson.)

"Marine vertebrate evolution as told by the tiniest fossils"

 Vertebrate evolutionary history is obscured by their generally poor preservation as fossils.
The numerous and articulated skeletal components are easily disaggregated and eroded beyond recognition
in most depositional environments. Teeth, however, are more easily preserved and can be small enough
to be incorporated as sediments in sedimentary rock, and their morphology is informative for diet.
Accessing these tiny isolated fossils requires the dissolution of sedimentary rocks and sorting processes based on mineral densities.
Here, I present data on vertebrate microfossils from different types of sedimentary rocks, and discuss the ways
these vertebrate occurrences change our understanding of marine predators in the early Mesozoic.
 This work provides new evidence for the ecosystem-scale influence of changing predation patterns on morphology and behaviors of prey.

"Memory System Design Using Emerging Technologies"

 Technology changes can bring fundamental transformations on how a system works.
As CMOS scaling reaching its physical limits and with the increasing demand for large volume
data applications and low energy devices, emerging technologies seem to offer promising opportunities.
In this talk, I will present the intriguing possibilities by the co-design of the device-circuit-architecture
in the context of emerging devices focusing on the memory aspect. 
I will discuss the feasibility of using Ferroelectric FET (FEFET) as a potential choice for memory
 exploiting its unique features. In addition, I will introduce how emerging technologies enable new features
such as Multi-Dimensional Access (MDA) in memories.
The MDA memory circuit transfers data both in horizontal and vertical directions
as opposed to the strict row-adjacency based memory transaction in conventional memories.
Many applications, especially vision and matrix applications frequently generate sequences of data requests
 that belong to different rows in the memory and are therefore less efficient.
This is solved by flexible access of MDA memories and would expedite applications from the fields of big data analytic,
 artificial navigation, and the Internet of Things (IoT) etc.
This talk will also introduce future research directions including the utilization of emerging technologies for hardware security.

"Reductions in the Undrained Shear Strength of Fine-Grained Soils during Earthquakes"


Abstract:  Dynamic loads can result in damage to buildings and structures, ground cracking and slope instability.
This presentation highlights the effect of plasticity characteristics and mineralogical composition on dynamic soil properties.
Extensive laboratory test results show that for two materials with the same plasticity index, the cyclic resistance in soils
containing montmorillonite as the clay mineral was substantially higher than the cyclic resistance in soils containing kaolinite as the clay mineral.
A relationship was established between the degradation in undrained shear strength and the post‐cyclic effective stress ratio (PC‐ESR),
which is defined as the ratio of the consolidation pressure to the effective vertical stress after cyclic loading.
Additionally, relationship between the ratio of the post‐cyclic undrained strength ratio with the undrained strength ratio
of a normally consolidated soil and the PC‐ESR was also developed.
Results from natural samples agreed well with the relationships developed from the laboratory prepared mineral mixtures.

"Linking the coffee in your cup to biodiversity in the field"


Abstract:  As human demand for coffee has grown, coffee has replaced forest throughout the montane systems of the tropics. Yet coffee,
 unlike most other crops, can be grown from full sunlight to deep shade. Does how coffee is grown matter for conservation of biodiversity?
 Does conserving biodiversity matter for coffee production? We know management of coffee agroecosystems can influence coffee’s potential
 to support mammals, birds and insects. How does coffee change the soil biodiversity that is largely invisible yet underpins all life on land?
 In this talk, I will present some of the research in my lab that explores the diversity of fungi that live in association with coffee belowground
 and discuss how the way in which coffee is grown, and those labels on the coffee we buy at the grocery store or our favorite coffee shop,
 affect belowground interactions between organisms and the long-term implications of agriculture for conservation of biodiversity and sustainability of agroecosystem

"Effect of Individualism on Online User Ratings: Theory and Evidence"


          Abstract: This research examines the effect of individualism on online user ratings. We develop a theory
based on expectation disconfirmation theory and prospect theory, and posit that user review ratings
by consumers from individualistic cultures (e.g., America), as compared to collectivistic cultures (e.g., China), are likely to be lower,
and the effect is moderated by customer-based brand equity and experience of premium product variants (e.g., business class travel).
We test our hypotheses on a data set gathered from online user reviews by customers from 166 countries
 for airlines across the world and find support. In addition, customer-based brand equity and experience of premium product variants
have positive direct effects on user rating valence. We also test our hypotheses on recommendation intent of users and control
for fixed effects and find support. Managerial implications and future research avenues are discussed.

"Overcoming Challenges in Agriculture Research"

                Abstract: Agricultural research faces many challenges towards increasing global food production and security. 
Some of the challenges include increasing production under drought, flooding, and increasingly variable weather conditions. 
However, opportunities to increase the capabilities of our food system can be exploited from five major scientific breakthroughs,
  use of a systems approach, sensitive field sensors, real-time data management, genomics in breeding, and the microbiome. 
A systems approach promotes collaboration and generates new avenues of research combining science, technology, policy,
and human behavior.  Deployable, sensitive field sensors can help pinpoint areas of need in a timely fashion
such as dry areas requiring irrigation.  Real-time data management allow the information obtained in the laboratory setting
to be transferable to the field more rapidly.  Breeding programs can exploit genomics using genomic selection or genome editing.
The microbiome is a new area of research that can be used to boost yields and resilience. Any and all five of these breakthroughs
can be exploited to help overcome challenges in agriculture research to increase food production and food security.
Bio: Kristin's education background includes a B.S. in Biotechnology from NDSU, a M.S. in Plant Sciences from NDSU
and a Ph.D. in Molecular Plant Pathology from Kansas State University.  Kristin has served

"Disaster Volunteerism"

Abstract: Volunteers are important contributors to response and recovery. Little is known about their engagement,
particularly in terms of comparing the engagement  of response volunteers to recovery volunteers.
This presentation reports the findings of a study that sought to explore volunteer engagement in response and
recovery in the case of flooding experienced by a number of communities in East Texas  following flooding in 2016.
Data was gathered through interviews with 72 response and recovery volunteers  and key informants,
an analysis of key documents, and first-hand observations. This presentation will discuss a list of factors that were found
to explain volunteer engagement in East Texas, note how these findings compare with factors suggested by the literature,
and suggest implications for disaster volunteerism more broadly.

Bio: Samantha Montano’s education background includes a B.S. in Psychology from Loyola University New Orleans
and a M.S. and Ph.D. in Emergency Management from North Dakota State University.
She is currently a Visiting Assistant Professor in the Department of Emergency Management.
