I recently had the privilege of delivering an expert lecture in a workshop titled 'Joining of Materials' at the prestigious Indian Institute of Technology (IIT) Delhi. The workshop was sponsored by the Science and Engineering Research Board (SERB) under the Department of Science and Technology (DST). The focus of my lecture revolved around the critical topic of failure characterization of solder joints using a fracture mechanics approach.

Solder joints are widely used in various industries, particularly in electronic packaging and assembly, where they serve as crucial connections between different components. Understanding the failure behavior of solder joints is of paramount importance for ensuring the reliability and longevity of electronic devices. To address this challenge, my lecture shed light on the application of fracture mechanics principles to investigate and analyze the failure mechanisms associated with solder joints.

Fracture mechanics provides a systematic and quantitative framework for studying the propagation and initiation of cracks in materials. By employing this approach, engineers and researchers can gain valuable insights into the fracture behavior of solder joints, enabling them to enhance their design, manufacturing, and reliability. I discussed key concepts such as stress analysis, crack growth, and fracture toughness, emphasizing their relevance to solder joint failures.

The lecture at IIT Delhi was a wonderful opportunity to share knowledge and exchange ideas with the bright minds in attendance. It was my sincere hope that the insights provided would inspire future research endeavors and contribute to the development of robust solder joint designs, ultimately leading to improved performance and reliability of electronic devices. I express my gratitude to the organizers of the workshop for inviting me to deliver the expert lecture.

A short-term course on Discretization Techniques is being organized from 05-09 June 2023 in Online mode at NIT Srinagar. The aim of this short-term course is to provide participants with a comprehensive understanding of these numerical methods and their applications in simulation. The course will also provide participants with hands-on experience using simulation software, enabling them to apply these techniques to real-world problems.

Experts from IITs, NITs, and professionals from other reputed organizations are giving their perspectives on discretization techniques with relevant applications. An important aspect of this STC is the structure of the program, where the emphasis is given to the interaction between the participants and the experts.

The student-teacher relationship is a kind of professional relationship and involves certain professional courtesies. Generally, most students are indeed very courteous in their behavior. Here are some suggestions for how to write an email to a professor. 

1-Open with a salutation.
Start your email with "Dear X," on a separate line by itself. This "X" could be "Dr Lastname" or "Prof Lastname", or, as is common in India, "Sir" or "Madam". If we are on first-name terms, it can also be only "Firstname". 

2-Sign off at the end.
At the end of an email, as at the end of a letter, it is good manners to sign off with something like a "Yours sincerely" or a "Best wishes" or even a simple "Thanks" if thanks are called for. Below this you should type your name. If you are in a tearing hurry then you may omit the signing off statement, but you must, at the very least, type out your name.

3-Write in sentences.
Write in proper sentences, as you would in a letter. This is not a text message, it is a formal communication, so do not use ellipses (i.e., ...) to punctuate your email. Don't break sentences across lines. Use fullstops and commas and other standard punctuation marks. And remember: begin your sentences with uppercase letters.

4-Don't use abbreviated words.
Usages like "thx", "c u" and other such are commonplace nowadays and they are, in my opinion, perfectly acceptable in electronic or written communications between friends, but not in professional or even semi-professional emails. So please avoid them entirely when emailing your Professor.

5-Don't use all uppercase.
ALL UPPERCASE IS LIKE SHOUTING AT SOMEONE. Please do not do this in professional communication.

6-Think before using emoticons.
Smileys are now commonplace in electronic communications and I feel that they can be used occasionally, and can be important in situations where you want to make sure that the recipient understands that you are talking in a light vein. In general, however, avoid using them in professional exchanges where possible.
