Teaching & Office Hours

In FA21, I am teaching two courses:

• MATH 205: Introductory Calculus I,
• MATH 440: Fourier Series & Partial Differential Equations.

CURRENT SP21 OFFICE HOURS: MWF 11-12
We'll talk more about this in class, and will pick a time based on a poll. I'll be holding virtual office hours this semester with regularly sceduled contact times. I'll be sitting at my computer, ready to help. The easiest way to get in touch is through email, but during office hours you can also reach me on the phone or have a video chat. My phone number and Zoom address are posted on Canvas. We will also be using the Canvas to host general class discussions. You can post, reply in a thread, and upvote questions. I'll generally wait a day or so before I answer questions to give your peers a chance to reply. More on this in class.

• Please ask general questions in the Canvas discussion board. That way everyone can see them and benefit from the answer, and maybe someone in class has an answer for you! If you have a specific question, you can always email me.
• via EMAIL: I'll try to answer general Disscussion questions directly on the dicussion board and mention in class, and reply to more specific ones via email. I get a lot of email, though, so put "MATH 205" or "MATH 248" to your subject line so that my email filter catches it. If it is urgent, use something like this "MATH 205 URGENT"
• via PHONE: I'll try to pickup/call-back during scheduled office hours. Email me if you want to talk outside of office hours and we can set up a time. See the course Canvas page for my phone number.
• Video: email to set up a time - Facetime, Zoom, Skype, WebEx, ...
• If you'd like to make an appointment for time not regularly scheduled, please check my weekly calendar for an opening and send me an email request. The link to my Zoom space is posted on Canvas.

• Calculus I : Math 235 (FA09,FA11,FA12,FA13)
• Calculus II: Math 236 (SP13)
• Calculs III: Math 237 (FA12,SP14)
• Linear Algebra and Differential Equations: Math 238 (FA13)
• Computers & Numerical Algorithms: Math 248 (SP10,FA10,SP12,SP14,SP19,FA20,SP21)
• Methods of Applied Calculus: Math 337 (FA15, FA18)
• Non-linear Dynamics and Chaos: Math 341 (SP17)
• PDE and Fourier Series: Math 440 (FA08, FA09, FA20)
• ODE theory: Math 441 (SP09)
• Numerical Analysis: Math 448 (SP16)
• Numerical Analysis for ODE: Math 449 (FA16)

Research Interests

I am interested in applying mathematics to physical problems. I have worked on problems from atmospheric science, coupled multi-physics, porous media, and nonlinear waves. I'm currently thinking about analytic continuation and ODE. I use both analytic and numeric techniques, while drawing on aspects of dynamical systems, PDE theory, functional analysis and numerical analysis. More specific information can be found here. Links to papers are found here.

I'm also involved in the M-cubed program, a six-week summer National Research Experience for Undergraduates Program (NREUP) funded by the MAA. Read more about the NREUP, and about the JMU M-cubed program. While the bad news is that we are currently unable to apply for the external funding that supports this program, the good news is that we are ineligible because JMU is national REU site!
